Its drugs...prescribed drugs for all kinds of ailments psychiatry type...we didn't have these shootings in the 50s....but we had the weapons...maybe not as automatic, but...weapons, weapons that didn't kill....not until the psyche drugs started....and its not the "tool" (as weapons are) that kill, its the person using the tool....making them illegal IMHO doesn't stop killings anymore than making killings illegal! stop the prescriptions of these drugs, you`ll stop the killings
