Not really, take a look at 1968. Federal troops were deployed in DC and to other Federal buildings during several of the Anti-War protests and Race Riots in the late 60s. Agreed it was to Federal Property, but Federal Troops were deployed. Federal troops were on city streets for the riots.
In 1970, while stationed at Ft. Meade, MD., I underwent training for riot and crowd control along with a couple of thousand or so additional troops stationed at Ft. Meade. Though never deployed the destination was to be Wash D.C. I do mean active duty federal troops, active duty Army, the war fighting Army, not National Guard.
Life is like a PB&J sandwich. The older you get, the moldery and crustier you get.
Now, get off my grass!
