"Here in Abilene, five people that we know of have been charged. Edgar Baltazar Garcia, Jason Middleton, Jeffrey Adams, Macheo Hill, and Jerry Sanders. They face a variety of charges involving the possession and selling of Cocaine, Methamphetamines, and Marijuana. There are Money Laundering charges, and a number of firearms charges as well. The next stop for them is Lubbock, where they'll stand trial in a federal courtroom. If found guilty, each of them faces life behind bars."

What is the relevance of this? Money laundering is rightfully a crime in its own right. Firearms charges are (usually wrongfully) separate crimes in their own right. Selling of cocaine & methamphetamines are covered under their own provisions much like marijuana is currently illegal even though alcohol is legal. The decision to legalize marijuana is not a decision to legalize cocaine or meth. In fact, most of the crimes here are only crimes because drugs are illegal in the first place, and if your argument rests on the 'associated crime' issue then the fastest way to eliminate the crimes associated with Prohibition is to eliminate Prohibition.
