But Bush and his cronies want to give them immunity for their crimes. Bush even said he wants to give them immunity for FUTURE crimes.
Then ALL the spy agencies can just claim the mean telecoms "gave us more than we asked for", and everyone is off the hook.
No independent body has done an audit of the FISA wire taps so we have no idea how much those are being abused. But you can bet it is at least as bad as the FBI abuses of the grossly misnamed Patriot Act.
If they weren't being abused, there is no need to change the law, since the 1979 law allows emergency wiretaps to last 15 days before the administration has to report who they tapped and why to the handpicked secret judge.
If they can't justify continued wiretapping they have to stop but they already have 15 days of information. They miss NOTHING because of the law. There is no reason to give them more power.
