Well Bruce, You see they're busy destroying what's left of America by engaging in politically correct "diversity forums" for the poor oppressed muslims who can't quite come to denounce 9/11, and attending local mosques (along with federal prosecutors) threatening potential "hate crime" perpetrators with harsh penalties.
So you see, they're too busy to deal with terrorists and terrorism (unless its a heterosexual white Christian male with the wrong accessory grouping on his AR).
