What are the odds? senator tell people that the thing everyone loves (guns) actually isn't the problem - it's those terrible, sinful things the bible was talking about that are the issue!
There seems to be a belief that people who perpetrate these murders have a big target above their heads, and creep around in black and white striped outfits waiting to strike... The idea that everyone having guns is a form of "protection" only works as long as you know that no-one with a gun would ever commit a murder.
The reality is that any Freedom Loving American (tm) has the potential to go on a rampage, and whilst the papers and newsstands will proclaim that it was "obvious" that he was going to be a killer, and point to a bunch of meaningless facts that supposedly demonstrate why he was a "bad guy", he obviously seemed normal enough up until the moment he pulled the trigger.
It's the Us and Them mentality that makes people think that guns are the solution, but eventually they'll have to realise that the mass murderers are being recruited from their own ranks of "ordinary decent citizens".
