Can you show me a picture of the said label? Or a link?
I cannot comment as I don't know the statistics for that, but as you're making a positive claim, you must provide the relevant statistics.
As another poster has pointed out, 1/5 of Americans are on these drugs so the odds of a shooter being on drugs is 20% without even factoring in the symptoms that led doctors to prescribe the said drugs.
I have no opinion either way but these are very hasty conclusions to draw.
I like your posts so please don't consider this condescending or insulting. I'm just looking for positive proof or the lack of it.
