1. The "facts" here have yet to be established.
2. I, personally, don't see any need to "counter" them, anyway. If people commit violent crimes, lock them up! My position is that - regardless of any crime statistics one might be able to dig up - it is no business of the Federal Government what kind of "high" I enjoy - alcohol-induced or marijuana-induced.

So, you maintain that continued, ongoing crime increases are perfectly acceptable, as long as the criminals are apprehended. Prevention is not important.
