Just a theoretical: what would happen if approximately 5,000 people were to show up at a District Attorney's office and place said public figure under citizens' arrest?
The charges? Aiding and abbetting suspected felons and accessory after the fact of a murder. Up to six counts, each.
Do you think there'd be any traction, there? Would the citizenry have a case?
There are no wrong answers here. Discussion is a participation grade for the day.
Please also consider the possibility of a change of venue, and possible federal invovlement for hate crimes.
