Millions of people have taken SSRI's and other anti-depressants for decades with positive results. Blaming the drugs is probably not anymore of an answer than better background checks on guns. Depression, though, can get so bad that it twists the mental apparatus totally out of shape. Many say that depression is anger turned inward. Besides wanting to end your own life, it makes you so roaring angry that you want to take others with you. In doc lingo, that's suicidal/homicidal. Perhaps a Valium wasn't enough or he needed talk therapy along with it (depressed people seldom feel there's anything wrong with their thinking--or if they do, they figure nothing will help, anyway, so why bother talking about it). Mental health shouldn't be ignored, but the drugs themselves aren't solely to blame.
