There was a LA County sheriff that got killed in the Mojave Desert, town of Lake Los Angeles a few years ago. They burned his killer out too.. he was a sort of a "rocket science" guy. He was building small rockets for some aerospace firm's experiments. A couple of days before he shot the cop, and some said the cop was a real ball-busting criminal but nothing corroborated those stories at all, his acquaintances were saying he was off his meds.
Dorner wrote about depression, depression rarely leads to violence so you can bet he was medicated for his depression and the meds led to the violence.
Meds are involved in ALL these shootings. So many Americans are medicated, it's unreal. A situation where the meds and guns don't mix is being created, they will use it to try to take away the guns of course... but if we are all high on something then why worry about getting shot, just take some more anxiety meds..
It's a safe bet that the MSM won't say much about meds and violence, their biggest accounts are with Big Pharma.
