The Slimes may be using TIA for political purposes, but that should not blind us to what a bad idea it is. Unless you can somehow guarantee we won't have President Hillary or her equivalent, or, more concretely, that an FDR, LBJ, or Nixon will never again be President, it is very difficult to see how TIA is a good idea.
Moreover, if we had:
1. Followed existing policy and procedure for dealing with terrorists.
2. Infiltrated Wahabbi mosques the way we infiltrate neo-Nazi organizations and Christian Identity "churches," we would have been well on the way to contering the threat.
3. Properly managed our borders - not "sealed" them, whatever that may mean - but just carried out the mission of the Border Patrol and INS effectively, 9/11 would have been reduced or perhaps even prevented.
Instead we are asked to swallow crap like TIA. No thank you. Not without better performance from existing security functions.
