Definition of “peaceful protesters” from a CBS article that the video was used in:
"Peaceful protesters" 1st amendment pepper sprayed?
“Thousands of protesters gathered near the Capitol, chanting "Free, Free Palestine," and some tried to block streets ahead of Netanyahu's speech, the Associated Press reported. Police wearing gas marks blocked the crowd — which was calling for an end to the war in Gaza that has killed more than 39,000 Palestinians according to Gaza officials — from getting closer to the Capitol.
The U.S. Capitol Police said on social media that pepper spray was being deployed because some members of the crowd had "started to become violent" and failed to obey an order to move back from the police line
After the protesters were turned away by police, they wound through Capitol Hill for several blocks before gathering in front of Union Station, according to the Associated Press, where protesters climbed the flagpoles outside Union Station and replaced the American flags with Palestinian flags. At least one person was arrested, and police again deployed "chemical agents," the AP reported, causing at least two people to be treated for chemical agent effects on the eyes.”
