Who will babysit the babysitters?

Can you remember ever seeing anyone on COPS getting wrestled to the ground after beating his wife and trying to kill the neighbors, and hearing the officers say: "Yeah, they always get crazy like this when they're on marijuana!"? Actually, I can't remember ever seeing a violent stoned person. Maybe pot doesn't make people violent. But, you know what can really turn them into rampaging maniacs, firing weapons in a home, killing the family pet, and pepper spraying an 11-year old girl? Being part of a marijuana bust.
