Alex Massie points out the inconsistencies that run through our politics:
...people who argue there's little sensible connection between Hollywood "violence" and real-world violence now suddenly insist that it just takes a silly poster and plenty of over-heated rhetoric to inspire America's Top Kooks to come out of the closet, all guns blazing. And of course the reverse is also true: people happy to blame Grand Theft Auto for just about anything now insist there's no connection at all between the tone of political discourse ("Second Amendment Solutions!") and some nut taking these notions just a little bit too seriously.
It's also instructive to imagine how different the reaction to this tragedy would be if its perpetrator were a Muslim.
