Rent-a-mob confrontations are pretty intimidating, to be sure, but perhaps a tactic may be borrowed from sweet corn producers. To keep predatory crop-damaging birds at bay, there are devices set up, using a propane gas supply, that simulate the sound of a shotgun being fired at irregular intervals.
A few of these set up at clandestine locations, can set off panic and consternation in the rent-a-mob, and bring the confrontation to the climax. A widespread stampede to get out of there is almost as effective as a mass arrest, and probably results in less hard wrestling by the authorities.
You don't have to actually have any Obamaphones. Just be ready to run when they get there.
Real question:
What if when they demanded “Come on out!”, I opened my front door & stood inside five feet back with a shotgun aimed dead level at the mob?
“Don’t you point that thing at us!!!”
“Come and take it.”
Take the keys out of the buses and watch them run all the way back home. LOL
