I've never used an illegal drug in my life (edit: not that it matters). But, I really don't care if someone smokes weed. I think it takes a certain dysfunctional personality to get worked up enough to go after someone selling pot so aggressively.
The real problem is that the people with the dysfunction are the ones attracted to positions which give them power over people. Some join HOAs and torture their neighbors about the height of a fence or color of paint. Others, like the law men in this case, abuse their discretion and the American taxpayer. It'd probably be a lot cheaper to get them all therapists.
