I wonder how many of the arrests on Scooby Doo actually resulted in a conviction.

It seems to me that a group of kids in a van full of pot smoke don't make very convincing witnesses. In addition to that, those meddling kinds would have contaminated the crime scene and ruined any possible evidence collection other than what looks like a forced confession. Speaking of which, wouldn't any decent lawyer be able to get that confession tossed out.
