I'd like to see profiling on these killers - Sandy Hook, Columbine, VA Tech, Aurora CO. I bet prescription medications are the common link. One of the Columbine killers had been prescribed Luvox, an SSRI. SSRI's are linked to suicidal & homicidal behaviors. American kids spend their childhood on Ritalin (an amphetamine) because they're diagnosed as "ADHD," then transition to anti-depressants when they're older. We've created these homicidal maniacs because we want a quick fix to our problems. Instead of taking the time to discover that our kids are having a reaction to artificial food additives that are producing "ADHD symptoms," or teaching them how to understand & handle emotions, we reach for the quick fix - which is not a fix at all.
