On the 8th of December, civil rights protesters had planned to stage a 4 1/2 hour die-in on the US Capitol West Lawn. They were met with threats and verbal aggression by the US Capitol Police. Since this was not intended to be a confrontational action, protesters decided to march to the US Dept of Justice and stage the die-in there.
The 4 1/2 hour duration of this die-in is the same amount of time Michael Brown’s body was left in the street by the police who murdered him.
