Throughout all the media coverage of the mass shootings in Colorado and Connecticut and elsewhere, I've seen little hints and tidbits about how this shooter was under a psychiatrist's care and that one was taking some sort of medication. Something like a fifth of the population in the U.S. is taking a mood-altering drug. Yet I haven't seen any stories tying it all together. Can anyone point me to that, or is it one of those topics that seems to be on the media's Ignore list?
