A civil lawsuit has been filed against the city of Morristown, Hamblen County [Tennessee], numerous police and deputies and other officials in U.S. District Court in Greeneville by Teddy Ray Mitchell, a disabled vet who is claiming various violations of his civil rights and for injuries he claims he received when he attempted to carry an American flag and a lawn chair into the location of an anti-immigration rally held last June in Morristown.

The brief complaint is here.
