I think there's a difference between crimanal drug usage and illegal drug usage. I mean, if it's a warehouse with massive ammounts of drugs in-out, then yes, a raid makes sense. There are criminals doing illegal things in there. However, a drug raid with the same tools preformed on an apartment is insane, it's going to be a group of people doing illegal things.

I will confess an error in my thinking, in that it's really hard to legally define what I describe, if not impossible. But, as the bible says (paraphrased, and this is probably the first time I've ever quoted it..) "I would not destroy the city if there is a single innocent inside of it." If you can't make the law work, than maybe it shouldn't be there.
