Protesters enraged by what they’ve seen today in the video of the police shooting of 17-year-old Laquan McDonald have taken to the streets of Chicago, with many marching peacefully, some interlocking arms to block intersections and others engaging police officers.

Though the shooting of McDonald by Officer Jason Van Dyke took place over a year ago, it was a lawsuit filed by an independent journalist that set a Nov. 25 deadline for the city to release footage of the incident. Well aware of the reaction the video would ignite, Van Dyke was charged today with first degree murder.

Not surprisingly, protesters hit the streets as soon as the video hit the Internet.
