Yep, I remember sit in, and lie ins. At least in those protests the hippies only got picked up and tossed into the paddy wagon, no fire hoses, mounted police or billie clubs. Just arrested.

I handcuffed myself to the door of my state capitol once a few decades ago. Left the handcuff keys at home, and epoxy in the locks while they were calling the cops.

The situation only lasted an hour but it was fun lol. Got a ticket for trespassing.
