The Dallas shooting happened after a peaceful Black Lives Matter event against the officer-involved shootings in Louisiana and Minnesota.

More than 300 people gathered in the humid and steamy early evening in Moore Square and named the latest victims of police shootings - Jai Lateef Solveig Williams in Asheville, a 35-year-old man armed with an AR-15 shot dead by police on July 2 after a chase; Alton Sterling in Baton Rouge, La., on July 5, and Philando Castile in St. Paul, Minn., on July 6. "That is not what that was".

The event was a carefully negotiated compromise between city officials and Black Lives Matter activists. Some attendees held up their phones and took video - an act central to a movement that has utilized cellphones to record encounters with police.

Demaria Laforte, one of the few at the protest Thursday to see the shooter, said while the protest might be her last, she knew there was no way everyone could be controlled and that there was still a possibility someone intent on violence might still show at a rally. It hurts me. I cried after each of the killings.

"All I know is this must stop", said Brown, "This divisiveness between our police and our citizens".

"I have profound respect for the peaceful protestors who marched in Philadelphia [on Thursday night] to demand change, and I have profound respect for the Philadelphia police officers who stood ready to protect them and who put their lives on the line for this city every day", Kenney said in an emailed statement Friday. "Until black liberation is won, we're not going away", Devika Ghai said. After hearing her friend was safe, Henderson said the impact of the tragedy heavily sank in. But I don't think that's ever what it is or has meant to be.

That sentiment echoed over the crowd as organizers read poems and wrote the names of individuals killed in the recent months on concrete. "The principal thing is love", said Chris Walton. "As a result, today we are seeing one of the noblest professions condemned by those who could benefit the most".

"The convenient narrative has been for people, for the media to say, "Well, this was organised by Black Lives Matter"," said Tezlyn Figaro, a publicist for Next Generation Action Network, the group that organised the event.

"If there's someone out there that was associated with this, we will find you and we will prosecute you, and we will bring you to justice", Brown said. "Let's continue our mission with integrity and professionalism". As past president of both the International Association of Chiefs of Police and Texas Police Chief's Association, we grieve the loss of these officers.

However, a law enforcement source told CBS News that monitoring of social media overnight indicated an increase of threats to police online, with one post saying "kill cops", CBS News senior investigative producer Pat Milton reports.
