Nearly all of the perps in these horrors had been taking psyc meds. These meds are well known to cause violent behavior and suicidal tendencies. Victims in the past have successfully sued the pharmaceudical companies so causation has been established. The profits from these known dangerous meds contribute a large amount to big pharma's trillion dollar bottom line. Since big pharma can pay for large amounts of lobbying to grease the palms of the best politicians that money can buy, we can expect this insanity to continue. So we will continue to blame the guns when the real problem is right there in front of us.
