The Bush/Cheney offices should all be armed with paintball guns. They won't hurt the protestors, but they WILL make them easy to find!
bearing in mind that this is an attack on campaign workers by union thugs with a long history of violence the idea of using a paintball gun that will only piss off the thug as a useful means of defending oneself strikes me as not very bright . REMEMBER THESE WORDS " I WAS IN FEAR OF MY LIFE OFFICER " "THIS MANIAC TRIED TO BASH MY BRAINS IN OFFICER " pepper spray is our friend so are pick handles ball bats etc,etc,etc.
