I saw the protest footage. This is a silly game they only stop the radical protestors when they literally step in the drive way of the facility.

Declare a 1000 ft "Federal Facility Protection Zone" using 40 U.S.C. ยง 1315
around all ICE facilties those rules are already being used around schools, courts and abortion clinics

just using existing facility protection law
