If you don't listen to me, liston Dr. Sanjay Gupta

aka CNN's chief medical correspondent: 

We still don’t know much about the shooter who lived in this home. But there is something else to consider: What medications if any he was on? I’m specifically talking about antidepressants. If you look at the studies of other shootings like this that have happened, medications like this were a common factor. Now I want to be clear I’m not saying that antidepressants can’t be effective. But people seem to agree that there is a vulnerable time. When someone starts these medications and when someone stops could lead to increased impulsivity and decreased judgment, and making someone out of touch. None of this is an excuse and it’s never just one thing. None of these behaviors will fully predict or explain why. But soon again there will be hindsight that might just help prevent another tragedy. It’s worth pointing out over a seven-year period there were 11,000 episodes of violence related to drug side effects. If there was a death involved, often it was the individual of himself or herself, a suicide.
