What was that argument again?

Hasn't one of the arguments for legalizing pot been that it will reduce crime since it will make marijuana readily available and there will be no need to secure it by nefarious means?

A couple of weeks ago, a legal pot dispensary in Colorado was robbed by a couple of bandanna and cowboy hat wearing bandits who pepper sprayed the workers. In another robbery, a man took a large amount of pot from a dispensary in Pueblo County.

What was that again about reduced crime?
