Dang, so sad. There are some very desperate people out there and the mentality is just to take, not make it for yourself. It's easier just to steal from others rather than just do for you and yours. Somebody willing to take it to the next level and kill a grower over some mj is a threat to society in so many ways. So scary.
I heard of a robbery in my area somewhat recently, nobody was hurt thankfully. I guess a truckload of guys pulled up with lots of guns, and raided this couple's grow barn while the couple watched helplessly from the house and said or did nothing. They didn't even call the cops.
