Definitely worth armed conflict and folks dying over stopping somebody from smoking pot ... Not.
One of my friends went out on a similar call. No Warrant, just a complaint from the neighbor about buyers and the strong odor of marijauna from the house across the street. Three cops, no tactical gear, a knock on the front door. The guy answered the door stoned and said “I guess you are here about my plants,” and let them in. He tried to pass it off as a medical grow (legal in WA) but he had too many plants. On a positive note, he was pretty good at growing, they were some of the biggest MJ plants anybody had ever seen.
I just saw that the guy hung himself in his cell. Ya sure he did.
