Exactly. It’s not the Ritalin or Prozac or other popular drugs. It’s the utterly unfounded belief that as long as someone “is getting help” (usually meaning drugs and occasional “counselling”), then it’s fine to let them roam around free even though they’re still obviously mentally unstable.
FYI. All mental health workers are required to report (to police)any person whom they believe is a danger to themselves or another. In the case of another, to let them know also.
The shooter was 18-19 and said to be ADHD. That I believe. It is highly unlikely he was taking any ADHD meds or receiving any counselling at the time of his shooting spree.
