NEW YORK (CBSNewYork) — Police were on alert in Brooklyn on Tuesday night for another round of violence stemming from a deadly officer-involved shooting.

Just like on Monday night, crowds gathered to protest the weekend police-involved shooting of what cops said was an armed 16-year-old boy.

As CBS 2’s Dick Brennan reported, Tuesday’s crowd was largely peaceful, but there was pushing, shoving and shouting and one arrest.

The crowd marched down Church Avenue in East Flatbush, to the 67th Precinct. The residents expressed themselves with loud, profanity-laced chants denouncing police practices, 1010 WINS’ Sonia Rincon reported.

Crowd Protests For A Second Night In The Wake Of Brooklyn Police Shooting

They were protesting the killing of Kimani Gray, who was shot by police when they say he pointed a gun at them.

City Councilman Jumaane Williams (D-45th), who exchanged heated words with NYPD Commissioner Ray Kelly at a committee hearing earlier in the day, was in East Flatbush observing the protest Tuesday evening.

“We want to make sure that nothing crazy goes on between the police and the people who want to express their views,” Williams said.

Monday night was a far uglier night, with bottles and fruit thrown, bus windows broken and a Rite Aid drug store ransacked.

After the violence, Gray’s family asked that another vigil for the teen be postponed. The family pastor, the Rev. Gilford Monrose, said Gray’s mother lost another son in a car accident just two years ago.

“The family is hurting – pain that is indescribable at this point in time,” Monrose said.

Kelly detailed earlier Tuesday what he believes took place the night before.

Police officers fatally shot Gray, a reported gang member, on Saturday, CBS 2’s Alice Gainer reported. Police said Gray pulled a gun on officers, but his family disputes that claim.

At the earlier committee hearing, Councilman Williams accused police of failing to address the needs of the community where the shooting happened.

Commissioner Kelly: “I noticed you didn’t mention anything about a 16-year-old with a gun the other evening that brought about this.”

Williams: “What you want to do is belittle the problems. We’re not going to pretend what happened yesterday is just one incident. It is not about the details of one shooting. It is about how you and the NYPD and the mayor have reacted to these communities.”

Williams: “I’ll cancel the rest of my afternoon and have you come to the community and walk with me and talk to some of the people so they can see someone cares about them.”

Kelly: “I go to community meetings all the time. I understand that’s a photo op that you would like.”

Williams: “It’s not a photo op.”

Williams also squared off with Kelly about police methods, including the stop-and-frisk policy.

Speaking about the events of Monday night, the police commissioner said that on the way to the 67th Precinct, some people stole fruit from local markets and threw the fruit and then the disorderly group disrupted a Rite Aid drug store on Church Avenue.

“They trashed the location. They took a man who was a customer. They tried to take the cash register. He tried to stop them. He was hit over the head with a wine bottle,” Kelly said.
