New terror worries

It seems to me the recent attempts to set off car bombs in London and Glascow may signal a move to less ambitious plots which would be easier to bring off and thereby harder to preempt. The overall consequence of a single Islamic idiot throwing a hand grenade into a crowded mall is potentially enormous. If that happened, of course, it would be protrayed gleefully by the loony leftists as a Bush failure to keep us safe.
