A certain expression comes to my mind when I see really stupid signs from evenm ore stupid people who think they are tough guys. My Platoon would make short work of these meatheads. That said,
the expression that comes to mind is:
DON'T POKE THE BEAR
Just a good piece of as of the moment friendly advice to the miscreants who think they are tough because the old people and such they assault in numbers cannot fight back.
I would LOVE to surround all these punks so none of them can escape, and close in on them and let the real fighting begin. NO prisoners. Each and every single one of them needs the living crap beat out of them so they will remember it till the day they die .
Screw the National Gaurd. Bring in some Marines or some Seals or Delta force or Green Berets.
They want a war? Really?
Let's give them what they want....
