What to do?

There has been a lot said about the horrific mass murders in Connecticut Friday. Many are calling for more and better gun control. (I'm, not surprisingly, one of these.)
Also we are starting to take a hard look at the way we treat the mentally ill in our society. You may have seen this post by a woman raising a mentally ill teenager. If you take nothing else away from the heart-wrenching tale, note that "Rikers Island, the LA County Jail and Cook County Jail in Illinois housed the nation’s largest [psychiatric] treatment centers in 2011." How sad is it that in order to get help, many parents have to have their children incarcerated?
Some are pointing to our desensitization to violence through movies and video games.
Others note that the media has sensationalized these mass killings to the point where it might appeal to an unstable mind to be immortalized in the headlines which will reliably follow a shooting rampage.
And finally, you might have heard Mike Huckabee and others suggest that because we don't have prayer in school and manger scenes at the City Hall, this is what happens. It's a bit of an over-simplification of what he actually said, but the basic point he was making was that the moral fiber of our nation is unraveling because Christianity has been "systematically" removed from public institutions. He was roundly attacked by "the liberals."
What Mr. Huckabee and his defenders fail to understand is that in the history of our nation, Christianity (at least his Bible-thumping version of it) has not been the integral part of our founding that they believe it to have been. In addition, just because the Constitution (very properly) forbids the government from establishing a national religion, does not mean that American citizens (even those in public buildings like schools) don't practice their personal religion in small private ways that are in no way illegal. This diversion into an aggrieved Christian's selfish lament is not helpful to the discussion we should be having. A prayer at morning announcements and the 10 commandments on a courthouse wall will not help.
Better parenting. Better health care -especially mental health care. Fewer guns and no semi-automatic guns. More involvement with our neighbors. Any of these, all of these might help. Bitching about how the government isn't sanctioning your religion over all others: not helping.
Let's not let these innocent little kids have died in vain.
