There was a post a couple days ago about how a town in Texas handled these CS’ers who intended to “protest” at a soldier’s funeral. IIRC, the motel where they were staying was identified and “by chance” locals with trucks parked them behind any vehicles with Kansas plates. Any that made it out found themselves being pulled over by the local constabulary and questioned about why they were in town and “oh, do you mind if I take a look in your trunk? You do mind (reasonable suspicion)? Well, OK, but we’ll have to stay right here or go to the station while we wait for a search warrant. Your choice, Pilgrim.”
Illegal search.
