This fear of "all cops" is irrational to the point I don't even believe it.
[Snarl! Spittle!] "I don't fear any cop!"
I believe STY hates "all cops", mostly like due to a traumatic case of butthurt over a parking or traffic ticket episode in which he is certain he was the victim of outrageous injustice.
He seems to want a society free of law enforcement on the premise that he can take care of himself. Yet who will enforce those little things like stop sign laws (probably the root of his anger) that allow the society we take for granted? Vigilante justice doesn't allow for investigation of past crimes, or at least not in any meaningful fashion.
And... oh, screw it. This topic is just too stupid to continue with.
