A comedian with a rare disability took to the Philadelphia Museum of Art steps Sunday morning to complete an inspiring challenge.

Steve Krause scaled the famous "Rocky" steps at the museum, after another comedian challenged him to climb to the top of the steps. He was born with a rare disability that keeps his arm and leg joints stuck in one position.

Krause is confined to a wheelchair, but tries to lighten his situation by not shying away from it and instead joking about it during his comedy routines.

"When I leave my chair at the bottom of those stairs and I look down on it, I know I've accomplished it, and I know I can do anything, because this chair does not define me," Krause told NBC10. "I define me. My heart and my mind and who I am defines me."

There are 72 steps leading up to the Art Museum.

Despite raucous moments as police and protesters in North Philadelphia went head-to-head Saturday night, police on Sunday said there were no arrests or injuries as a result of the demonstration.

Philadelphia's demonstration without arrests stood in stark contrast to others across the nation, some of which left officers with injuries and protesters in handcuffs.

Groups of protesters numbering in the hundreds took to the streets in Philadelphia each day for half the week, after controversial deadly shootings by police in Baton Rouge and Minnesota stoked outrage across the nation, again stirring the "Black Lives Matter" movement into action.

Friday and Saturday's protests came on the heels of an attack on police at the end of a protest in Dallas Thursday night that left five officers dead, seven others injured and two civilians wounded. Police have said so far that the gunman acted alone in that shooting, but the investigation is still active.

Philadelphia's protest Saturday night marked the most aggressive demonstration so far, with video showing police and protesters physically clashing outside the department's 24th and 25th District headquarters, on Whitaker Avenue near Erie. Protesters vowed to "shut down" the districts, saying they were responsible for perpetrating brutality.

Another protest is expected to begin at 7 p.m. Sunday at 40th and Market streets in West Philadelphia, NBC10's Drew Smith reported Sunday afternoon.

Former Philadelphia Police Commissioner Charles Ramsey told NBC News Sunday morning that the United States is "sitting on a powder keg" as tensions between police and communities across the nation boil over into tumultuous and sometimes violent protests.

Ramsey, who passed the helm of the Philadelphia Police Department last year, was tapped in 2014 by President Obama to lead his Task Force on 21st Century Policing. The White House established the task force to take a hard look at police-community relations in the wake of calls for more police accountability and a number of earlier killings by police that stoked controversy.

"You can call it a powder keg, you can say that we're handling nitroglycerin," Ramsey told NBC News' Chuck Todd on "Meet the Press." "But obviously when you just look at what's going on, we're at a very critical point in the history of this country."

Ramsey went on to day that he fears the Republican and Democratic National Conventions won't go off without some kind of incident occurring. The climate is simply too volatile, he said.

"[The conventions] are going to be very challenging to handle, and I don't think they're going to go without some incident taking place. It's unfortunate, but that's what I personally think," Ramsey said. "I hope that's not the case, but you've got too many people that are now with this extreme rhetoric, and that is just not good for anybody. We need to come together. We need thoughtful people to sit down and engage in dialogue and actually come up with solutions."

Ramsey also talked about the vast differences among police departments across the country, saying that training and standards need to be made more consistent across the board for all law enforcement. Todd pointed out that many of the police-involved incidents that have sparked protests and outrage have occurred in smaller suburban police departments.

"There are approximately 18,000 police departments in the United States. In my opinion, that's far too many," Ramsey said. "In your larger cities, where you have a lot of diversity, obviously you have officers that are very accustomed to dealing with a variety of people. We still have parts of our country where that is not the case."

In Philadelphia, Ramsey placed a heavy emphasis on community policing, putting new recruits out on the street in some of the city's most challenged neighborhoods to interact with citizens on the ground level. His eight-year tenure leading the city's police force boasted a drop in violent crime, with the city recording nearly 150 fewer homicides in 2014, toward the end of his leadership, than it did in 2007 before he took the reins.

Ramsey also gained notoriety in the city when he called for the United States Department of Justice to come review Philadelphia's police-involved shootings at a time when they seemed to skyrocket in the city.

Ramsey cautioned against reading too far into statistics recently published by the Washington Post saying that police killings of civilians and police being killed in the line of duty are both up this year compared to last, warning people to keep the numbers in context.

"We do have some rising crime rates, and let's face it, we have on average about 13,000 murders in the United States every year. These are not shootings by police. These are people killing people," he said. "There's a disproportionate amount of it going on in many of our more challenged communities. Who do you think goes after the people responsible for these crimes? It's the cops, and we encounter a lot of very dangerous people out there on the street."

He also told NBC's Todd that he agreed with FBI Director James Comey's worry that police may be hesitant to act as aggressively now in light of recent events and officers' actions immortalized in viral videos. Both Ramsey and Comey did point out that no official statistics have shown this phenomenon, sometimes referred to as the "Ferguson effect."

"Police officers are human beings, and when you're being attacked like that, or at least you're perceived of being attacked, it does create some issues and some problems," Ramsey said.

"I think we all need to recognize that there are changes that need to be made," he continued. "We can't look at it from a defensive posture. How do we move forward? How do we create an environment where we're on the same page? There's only one issue, and that's creating safe neighborhoods, but also neighborhoods where people who live in [them] have a sense of justice and fairness as the law is being applied."

An African American police officer has a message for America in the wake of the recent deadly police-involved shootings of black men and the deadly sniper attack on Dallas officers: stop the madness.

“That’s what’s going on,” Atlantic City police officer Mike Braxton said. “It is complete chaos and madness.”

Braxton, who has been on the force for nearly nine years, released a Facebook video reacting to last week’s shootings. Braxton says that as both an African American and a police officer, he began to feel overwhelmed and pulled in two different directions by people on both sides who wanted to know his opinion. 

“Both sides were trying to pull me to choose sides but that’s not what we need to do here today,” he said. “Our voices sound the same.”

Braxton believes both African Americans and members of law enforcement feel similar emotions.

“We’re feeling the same exact way but we’re both yelling so loud that we’re not hearing each other,” he said. "You have to listen and sit down and talk to come up with an agreement.”

Braxton told NBC10 he initially thought about writing his message in a post but his girlfriend urged him to make a video instead.

“My position is to pull everyone together,” Braxton said. “Because if we stay quiet we let the evil talk. We let evil speak for everything that we’re not even thinking.”

Braxton works in the police department’s office of community relations and spoke Monday at Sovereign Avenue School in Atlantic City with children enrolled in the city’s Junior Police Academy. Braxton says his message of unity doesn’t discriminate.

“Hopefully this reaches someone that needs it,” he said. “And that person’s name is America.”

Law enforcement agencies across the region are dealing with community reactions, both positive and negative, to the recent police-involved shootings of black men in Louisiana and Minnesota as well as the sniper attack on officers in Dallas.

Philadelphia Police Commissioner Richard Ross has observed the many protests in Philadelphia, including a demonstration in North Philadelphia Saturday in which protesters insulted officers, calling them pigs while chanting, “F*** the police.” Those involved in Saturday’s protest, which was organized by the Philly Coalition for Real Justice, say they targeted Philly’s 24th and 25th District due to what they believe is a history of injustice against black and brown people in the community.

“They have every right to protest what they believe are injustices and that’s okay,” Ross said. “But to have someone in your face, an inch from your nose, calling you everything under the sun, you don’t go through training and magically become a robot.”

Despite the tension, no arrests were made during the demonstration and the officers stood silently for the most part as the protest went on. Commissioner Ross told NBC10 he was proud of the restraint the officers showed.

“I couldn’t have been more proud of them,” Ross said. “They were professional. They were patient and I admire their resolve.”

Police departments in other parts of the region have received messages of support from their communities, including cards, letters, food and donations. Frank Engro showed up to the Whitpain Township Police Department bearing food and Wawa gift cards.

“They had a hard time last week,” Engro said. “What could you do for people other than have a lunch on me? I can’t take all these people to lunch so have a nice lunch on me.”

Whitpain Township Police Chief Kenneth Lawson told NBC10 the gifts were unexpected but the department is grateful.

“No police officer wants to ever harm anybody,” Lawson said. “We always want to do what’s right for the community. If we constantly do what our public expects of us we will overcome this.”

Lawson, who has been on the force for more than 30 years, said he’s never seen anything like what he saw during the attack on Dallas officers last week.

“Never in my career,” he said.

Lawson told NBC10 many of the items donated to his department will be donated back to the community for people he believes need them more than they do.

Hatfield Police Chief William Tierney told NBC10 his department received similar support from their community.

“The words that people use, they use adjectives that really are heartfelt,” he said. “The messages are really deep and I think they really reach the officers on the department.”

Chief Tierney also acknowledged however that more work needs to be done. 

“I don’t think any community is immune to any type of racial divide,” he said. “But I think our department is very well educated and that we work every day to communicate with people of all races. We as police must be kind and respectful to everyone. It’s going to make a difference.”

A volunteer firefighter died from his injuries after he fell during a training exercise in Georgetown, Delaware.

The incident occurred Monday around 6:45 p.m. at the Delaware Coastal Airport on 21553 Rudder Lane. The Delaware State Police Aviation Unit was conducting a routine training exercise with the Delaware Air Rescue Team(DART), which is made up of volunteer firefighters throughout Delaware.

During the training exercise a pilot, trooper medic and two volunteer firefighters were on board a helicopter. One of the firefighters stepped out onto the skid of the helicopter and fell from an unknown height onto a grassy area below, officials said.

Police later identified the deceased as Tim McClanahan, 46, from Lewes, Delaware. Medics took McClanahan to Beebe Healthcare where he was later pronounced dead.

The Lewes Fire Department also released a statement on his death on Facebook.

"It is with deep, deep regret that the Officers and Members of the Lewes Fire Department announce the passing of one of our own earlier today," a spokesperson wrote. "Further details on remembrance services are to follow."

Gov. Jack Markell also expressed condolences:

"My thoughts and prayers go out to Mr. McClanahan’s family during this difficult time," said the Democrat in a news release. "He was an exemplary public servant, who volunteered to serve his community despite the risks of being a firefighter. The greatest honor we can pay to Tim and his family is to keep his memory alive, allowing his dedication to serving the public to continue to inspire us, while reminding us of the sacrifices our first responders, police officers, and firefighters make every day to keep us safe."

Both the Federal Aviation Administration (FAA) and Delaware State Police are investigating the incident.

Friends and family gathered to mourn a teen boy who drowned last week in the Delaware River.

Investigators say DeAndray Lindsay, 16, was swimming in the Delaware River Thursday along Delaware Avenue and Beach Street in Philadelphia around 5 p.m. when he went under the water and never surfaced. The Marine Unit arrived at the location and pulled Lindsay out of the water. The teen was taken to the hospital where he was pronounced dead at 6:39 p.m.

Loved ones gathered at Penn Treaty Park Monday night during a vigil for Lindsay. They brought balloons, lit candles and said their final goodbyes to the teen. Lindsay’s family created a GoFundMe page to raise money for the teen’s funeral.

An investigation is underway after someone made a bomb threat against three Philadelphia police districts, according to officials.

Officials say a person alerted a 39th District officer about a message on Facebook which stated someone would blow up three Philly police districts with a bomb.

“We received information that there have been threats made against several of our patrol districts,” a Philadelphia Police spokesman told NBC10. “Obviously, we are taking this seriously and it will be thoroughly investigated in order to ensure the safety of not only our employees, but the residents who live in the aforementioned districts.”

The threat comes less than a week after a gunman shot and killed five police officers during a protest in Dallas. Police departments across the country have been on high alert since the incident, which was the deadliest attack on police officers since September 11, 2001.

Rehoboth Beach Police have arrested a man after he allegedly refused to leave a Delaware amusement park on Friday.

Hank B. Destefano of Pleasant Valley, New York, was arrested for resisting arrest after police responded to a report of a verbal argument at Funland in Rehoboth Beach, Delaware. Upon arrival, police observed Destefano repeatedly yelling profanity in the presence of families and children, according to investigators.

Police say Destefano acted aggressively toward an officer and threatened to assault him. After appearing to calm down, Destefano then began struggling with the officer after he was placed in handcuffs, officials say.

After being placed into the back seat of the patrol car, Destefano allegedly attempted to kick the rear window out of the car. He was transported to Rehoboth Beach Police Department where he urinated on the floor and repeatedly stomped in it, officials said.

Destefano is charged with resisting arrest, failure to comply, and disorderly conduct. He was committed to Sussex Correctional Institution. 

The 8-year-old Maryland boy who had been hospitalized after nearly drowning on a Caribbean-bound cruise ship after it left New Jersey last month has died, officials said Monday. 

Royal Caribbean confirmed Prince Adepoju died on July 2, two days after he had what the company described as an accident in one of the boat's pools. 

"We are heartbroken to learn the news," the cruise ship company said in a statement. "Our thoughts and prayers are with the family at this terribly sad time." 

The little boy's family could not immediately be reached for comment on his death. The medical examiner ruled drowning as the cause of death, and said a seizure disorder was a contributing factor. His death was ruled an accident. 

Adepoju left from Bayonne June 30 on the Anthem of the Seas cruise ship around 4:30 p.m. The ship returned five hours later after the boy was found unresponsive in the water; Coast Guard officials had said the boy was likely in the pool for eight to 10 minutes before he was pulled out. 

The child had been in the intensive care unit at Staten Island University Hospital since the accident, according to The Staten Island Advance.

A dump truck overturned Tuesday morning, blocking traffic along a Montgomery County road.

The orange dump truck flipped onto its side along Conshohocken Road between Ridge Pike and W Elm Street in Plymouth Township, Pennsylvania around 5 a.m.

No one was seriously hurt.

After a little more than an hour, crews righted the truck. They said the crash could tie up the roadway through the morning commute so try to avoid the area and use alternate routes.

WHAT YOU MISSED YESTERDAY

Pa., Del. Look to Tax Mileage, Not Gas: How far you drive could wind up costing you more than just the price of gas. The I-95 Corridor Coalition, which represents a group of East Coast states including Pennsylvania and Delaware, is trying to do away with the gas tax and instead charge drivers a fee for the miles they travel. The Washington Post reports that the states that make up the Coalition — Delaware, Pennsylvania, Connecticut and New Hampshire — recently applied for a federal grant to test the idea. Officials would put together the policies and technologies needed to count the miles driven by 50 recruits from each of the four states. They would send out "faux invoices" monthly, and would collect the data that legislatures — and the driving public — would require to decide if the change makes sense. Coalition executive director Patricia Hendren said people could opt out of the mileage tax and instead pay an annual fee.
