I was reading this piece a couple of days ago. It caught my interest.
There’s another report out of Florida: http://www.cchrflorida.org/antidepressants-are-a-prescription-for-mass-shootings/
We are making a couple of bad assumptions here...in that murder/homicide are our only ‘flip-switches’. I think if you get into violent assault, and lesser crimes...other obvious things will be attached to the prescription drug trend.
