Kill them! Make sales, possession, and being under the influence of methamphetamine or any of its analogs a capital crime: No appeals, done on the street corner by the local cop. Sure, you'd have a few who would "make bad choices" but at least YOU wouldn't be inconvenienced at the Wal-Mart.
Why should law-abiding citizens be inconvenienced because of the activities of a bunch of criminals?
Look, I'm a major supporter of law enforcement (I come from 3 generations of NYPD) but I'm sick and bloody tired of laws being passed that don't do a damned thing about real criminals and just make life for every day law abiding folks more difficult.
Actually, if you want to kill someone, MY vote goes to killing anyone who has anything to do with passing, enforcing or encouraging the passage or enforcement of any law which attempts to prohibit what a grown individual can put into his or her own body, whether that substance be heroin, speed, pot or transfats. Of course, the person who chooses to ingest such things should have NO CALL on anyone else to pick him or her up out of the gutter when they DO ingest. I had family members (in-laws) who did drugs and I refused to allow them around me unless they were (and stayed) stone-sober. But I would have cut my own tongue out before I would call a cop on them. Eventually they either sobered up or they went all the way under. Either way, their choice and nothing I could do to prevent anything.
