Medical marijuana dispensaries have traditionally brought higher crime because of the inability to take credit cards. This makes it a high cash business with substantial risk during close of business.
Sunday night a Seattle, Washington dispensary owner was leaving his store when he saw someone lurking in the area of his store around 11:30p.m. The two men got into a confrontation - words were exchanged and then the lurker made a sudden judgement.
Thinking he was being robbed again, the dispensary owner fired his shotgun (I'm not sure how he was concealing it of if the lurker was just oblivious) striking the man once. The lurker wobbled away with the owner following him and applying first aid until authorities arrived.
