1:40 p.m. As tens of thousands of peaceful marchers flooded New York City streets Monday evening, just before 7 p.m, NYPD officers were overheard chattering on the citywide police scanner threatening physical violence against protesters.

At around 6:20 p.m., marchers headed to the 77th Precinct in Brooklyn and had surrounded it. One person called in to describe the scene.

“There’s a group headed the 77th Precinct there’s a group, may be heading towards there please.”

Another voice responds: “Shoot those motherfuckers.”
