Reply #21: You don't want to hurt people. You don't have to be a bully.

Wasn't it Bruce Lee who said "Be water, my friend!"

If you can't BE water, at least use it! No fire hoses, though--just a persistent, gentle but cold rain, coming out of the sorts of sprinklers one would use on a suburban front lawn. If you're lucky enough to have a stiff breeze on the day in question, your job will go faster.

After you isolate your group of linked-arm/seated enthusiasts, you can go around behind them and start folding up their things and tagging/boxing them, loading it all on hand trucks and carting it off to a lost-n-found or property storage facility.

If you really want to be a bit vicious, and play on basic needs and wants, have a food truck come by and prepare hot chocolate and cinnamon buns, and maybe some nice hot coffee, too, for the enforcement personnel--and anyone who gets on the detention bus.

If cold water and a chilling breeze won't move a person, the smell of cinnamon rolls and hot chocolate or coffee just might.
