So make it efficient and ethical. I'm all for accountability. But you are the one who is stupid or naive if you think we do not need a national police force of some kind. I'm sure Al Qeada would love to have no FBI to worry about.
With the way the FBI has been handling Al Qaeda they might as well not exist for all Al Qaeda is concerned. You want to make terrorism a risky gambit on American soil? Announce that every intelligence agency has been given the green light to use any means necessary to extract information from terrorist-prisoners. Then follow that up by announcing that the military will be order to shoot to kill any individuals engaging in an act of terrorism and that the lives of hostages will be disregarded by the military while it is carrying out its mission. That would do two things: show Al Qaeda that we are deadly serious and tell them that there are officially no "human shields" anymore. And just for good measure, in major areas like NYC and DC, put SAM batteris on the police force's buildings' roofs which can be used by special police units to shoot down any hijacked aircraft if a F-15 cannot get to them first. Sending the FBI to fight Al Qaeda is like sending Jimmy Carter to play hardball with Castro.
I'll pray for you and for our Republic.
