I think there was a typo in your title. I think it should read, "ACLU Comes Down on the Side of the Bill of Rights."
The ACLU wants to know, among other things, how the agency chooses whom it will interview.
Yes, they want the FBI to interview equal numbers of other ethnic groups in the building of a terror database, in that way hard disk drive makers will be the real winners in the war on terror. Do you really think the ACLU cares about the Bill of Rights, or are they using the Bill of Rights as a tool to acomplish some other agenda? I think they want the government to stop questioning and incarcerating people we capture in the investigation into international terror. If they get their way on this they will go on to something else, like open borders with Mexico and Canada. Don't bring the Bill of Rights into this arguement. The terrorists that were released because we did not have evidence to charge them have rejoined the fight as our enemy. (So why provide the Bill of Rights to our enemy?)
Does the "Bill of Rights" apply to terrorists? Do we Americans have some kind of a perverse, purist death wish that causes us to lose our common sense during time of war?
