I can't say the police haven't done anything to bring this kind of shit onto themselves, it just takes a modest number of well-publicized abuses of power to piss off the populace pretty royally...and there are plenty of hard-cores both Left and Right who eagerly publicize those real abuses. However, what Obama wants is going to require real legislation, not Executive fiat, and that is just not going to happen during the remainder of his term.
