Wall-to-wall media coverage, along with saturation internet talk, gives the nutters their chance at the limelight. Schools need to enlist some protection from the community to make sure these fools get their wish of getting their heads blown off if they they try something stupid.
Not to mention the Johnny Jihads that now see an opportunity to reek chaos so close to Christmas/Mayan Calendar End Times.
24/7/365 media coverage is to blame, IMHO. It’s giving all those nuts a way to go out in a “blaze of glory”.
