Faced with a police force that has already fired on three innocent citizens in pursuit of suspected murderer Christopher Dorner, LA residents are taking it upon themselves to warn area cops that they are not, in fact, the so-called "killer cop" everyone is looking for. Rather, they're just bald black people or people driving pickup trucks.

The joke's on these people, though, because of course the real Dorner would wear a shirt that said he wasn't Christopher Dorner. He's not stupid. Don't be surprised when a sign like this ends up with a police bullet hole through it.
