I think Blake could be convinced a few of those crimes are "go home and sleep it off-slash-don't let me see you around here again this week" situations, sure!! I mean, public intoxication is hardly a crime, right? Pfft.

On the other side of things, Blake's always looking to help out the kids, so maybe he and Pepper know each other from that. John could/would volunteer at the schools or coach little league in his spare time. \o\
