Many many helicopters hover above the streets. Full riot gear was worn by some officers during the ordeal. Rubber bullets and other projectiles were in use. The police were very aggressive. All this over chalk painting on the sidewalk?
In the video @ 4:49, you can see a man in a white t-shirt shot at very close range with a projectile weapon. He falls to the ground and is clearly incapacitated. The police then run up and violently kick him in the face while he is laying on the ground. He is then taken away in cuffs.
