In the state of Washington, marijuana thieves and medical marijuana users have clashed, sometimes deadly ways:

In the past week, a man in Orting, Wash., near Tacoma, died after he reportedly was beaten while confronting people trying to steal marijuana plants from his property. On Monday, a prominent medical-marijuana activist shot an armed man who is accused of breaking into his home in a suburban area near Seattle where he grows and distributes marijuana plants.

Thank goodness the second victim was able to exercise his second amendment rights. But right now the state government of Washington wants to reexamine "how it regulates the drug." How's this for an idea: just legalize it, all of it. My bet is that violent marijuana robberies would decrease with legalization.
