The war on drugs has made dangerous people insanely wealthy, its made the drugs more potent, its made them more dangerous and more addictive, and made their addicts more desperate. All you're doing when you shoot a drug dealer is thinning down the competition for someone else... when you decriminalize you neuter the organized crime. Someone who has nothing to lose isn't going to not deal drugs because you might kill them if they get caught. Its really hard to understand how people don't see this simple fact.
