The fact the officer was an Iraq veteran may have something to do with it. I was a soldier(in training for special forces) who served during the first gulf war. Bizarre, “triggered” violent behavior is not uncommon in vets. It’s graciously called PTSD, but the side effects are sometimes more severe than are publicized. I remember one Marine in California who was scheduled to ship back to Iraq the following day, posting himself at a 711 with an AK47 machinegun, where he gunned down the responding detective. That video was suppressed, because they were doing heavy recruiting at that time. There was a Navy Seal who ran down the Las Vegas strip whacking people in the head with a pipe. My old team leader(an experienced SF officer) disappeared then showed up stocking cans in a grocery store in the Southwest, where he took up Reiki spiritualism and specializes in “forgiveness” and “healing”. I got out before I had to serve overseas, but almost everyone I know who went was affected. Just please investigate the war vet angle in this - we may discover some things we don’t want to admit.
