WASHINGTON -- Congress is moving to require videotaping of interrogations of detainees held by the military, a step proponents say will prevent abuse and create a valuable intelligence record.

The provision, which the House passed on Thursday as part of the 2010 Defense Authorization Act conference report, would apply to interrogations of anyone held at a Defense Department facility. Because the Central Intelligence Agency's secret overseas prisons have been closed, it would most likely cover terrorism suspects whether they were questioned by a military or a C.I.A. officer.

The requirement would not apply to battlefield interrogations by troops engaged in combat.

This bill is suppose to "prevent abuse and create a valuable intelligence".  I'd like to know how? 

If the bill Senator Joe Lieberman has put forward is passed, all Congress has to do is turn around and exempt any future videos as well, siting the potential effect/harm on American national security or our troops-- "Americans can't see those videos, they might bring harm to our national security or our troops."

So why bother with this bill demanding that interrogations be video taped -- they will never see the light of day anyway with the likes of folks like Senator Lieberman in Congress.
