Now that the shooting has been largely sorted out, and all the relevant facts known, I can say that most of what is going on is depressingly predictable.
Already some of the best-known whack jobs in the house have rolled out gun control legislation almost as though it had been moldering in their desks for the last 4 years, a tacit admission that unless you represent a very safe district, supporting gun control is an invitation to disaster. Current offerings would revive the "assault-weapon ban" and ban sales to people adjudged to be mentally unstable, neither of which would have affected the outcome of the shooting.
Expanding on this, one other offering would ban criticism of elected officials, lest the "dear leaders" be offended or something, and another would bring back the "fairness doctrine", AKA the "Hush Rush" bill, again the primary objective being to silence dissent in any form.
What kind of government wants to disarm its citizens, and prosecute dissent?
One more thing: In my lifetime I've seen a few politically motivated assassinations. Since 1960, how many of the assassins have been right-wingers? I don't remember any.
Aside: How long will it be before someone on the left accuses Rush Limbaugh of being the spotter for Sarah Palin over on the grassy knoll?
