Yep. Some people have been saying it and saying it. There is a strong correlation between psychotropic drugs and aggressive behavior/mass shootings/suicide. The mainstream media largely ignores this probably because of the high advertising revenue they receive from the bazillion dollar Big Pharma industry. For whatever reason MSM has not followed the very strong connection.
For my money psychotropic drugs would be the lead I'd follow. But I'd put my real money on the federal government doing next to nothing about the drug connection. If there is a serious government investigation into psychotropic drugs and aggression, mass murder and/or suicide look for it to be conducted with Big Pharma playing a major role; look for it to take years; look for the results to be next to worthless. Oligarchy don't cotton to the masses feckin with their cash and control cows.
