This happens all the time, and it usually doesn't make the papers.

Gunmen break into homes, demanding pot, sometimes murdering the occupants. Worse still, fighting back is a virtual death sentence.

Usually these goons wear bulletproof vests and blue shirts with yellow letters spelling out DEA. Sometimes they're anti-social characters from that same gang that harasses, intimidates, and even threatens to make up charges on the spot.

Today in Tucson, it may have been another group, although it's hard to tell from the story. Expect a manhunt; the government hates competition!
