Would Crime drop tremendously if IT was Legalized? (for certain countries)

[Lynexon]

I personally don't see why Marijuana is illegal in the U.S.  It is the least harmful of any "drug" (since it isn't normally modified like coke or heroine or made like crack, X or pills, i don't consider it a drug since it used to be a listed herb), and is especially less harmful than Alcohol, and isn't as addicting or near as harmful as hard drugs  Scientists have proven it yet it is still illegal.  Honestly, when is the last time you ever heard of someone getting stoned and beating the hell out of his wife?  When is the last time a mother got stoned and beat her kids?  Also, alot of people wouldn't have permanent records of getting caught with a joint in their teens.  Alot of people I know who do it are peaceful people and aren't crazy or stupid.  I want to hear ppls thoughts on this.
