I read that comic and I just can't help but think "Why doesn't mister Smythe just call the cops?"
I get the message that he's trying to convey, the role reversal and all that, but it just doesn't jive for modern society. If a random group of assholes tried to "discover" someone's house in today's society, the local PD would come on by to taze 'em in the taint.
