I confess that I'm starting to get numb to the constant misuse and dramatic overuse of the language by progressives of all political strips and I failed to even notice until you pointed it out.
It is what the left does.
Words have no solid meaning, they shapeshift.
It is what they are trying to do to the constitution.
What gets me about this attack is the James Dean-style game of chicken element about it. The Boston Marathon is heavily defended by hundreds of cops. These guys carried out the attack right under their noses. McVeigh parked a vehicle in front of the Federal building like every other visitor. James Holmes attacked a movie theater full of civilians. The Bali bombers hit a nightclub where the toughest resistance might have been the unarmed bouncers. The 9/11 attackers hit planes full of civilians.
Another point is that the Chechen brothers did not go house to house blasting away at civilians. They carjacked a guy and let him live, which allowed the guy to alert the cops. My sense is that while they, as Chechens, had the inborn temperament of stone killers, something held them back in a way that did not occur with other spree killers or Islamist terrorists.
