What's Behind the Epidemic of Family-Killings? Could it Be Anti-Depressants?

Psychologists say a bad economy can create a family annihilator like Bob Dylan's Hollis Brown, who "looked for work and money … and walked a rugged mile" and whose "children are so hungry that they don't know how to smile," until he kills his wife and five children in a mercy massacre. 

And that's before you get to the added threat of losing your wife and kids, which produces a feeling of loss of control in the killer-to-be, say psychologists. 

But of course the elephant in the room is: When people lost their jobs or wives in the past, they didn't kill their entire families in a burst -- make that gun burst -- of irrational rage. Not every week.
