The other persons of interest didn't wait for the LEO'S to show up in order to make a statement. The active warrants thing comes to mind. Had a guy come to my place to shoot back about 15 years ago. I had worked with his dad about 30 years before that. This 28 year old seemed to be a good guy, but with 5 kids with 4 different baby mommas plus his current squeeze, he was always at war with somebody. He brought two Glocks with him, but was a poor shot with either of them. I had three plates and a paper target stand, but 50 rounds down range got him about 6 hits. Sounds like the mall shootings. I heard through the grapevine that a couple of a daughter's ex-boyfriends popped some rounds off in a mortuary over the mom's casket. Cleared the whole place out in seconds. Ain't anywhere safe these days.
