I've posted this in Comments a couple of times. I think this sums it up. Please feel free to send to your Congressional delegation -- perhaps written in crayon, so they'll understand.
1 There's a law (FISA).
2 The law sets forth provisions for "domestic spying."
3 The law is clear, and carries criminal penalties.
4 If Bush didn't like the law, tough -- he could've asked Congress to change it, but he didn't.
5 Bush authorized breaking that law; and admits it.
6 Bush should be impeached by the House, tried and convicted by the Senate, then jailed for this High Crime.
