Personally I don't see the big deal of monitoring phone conversations either. Your cell phone conversantions and any internet messages you send can already be monitored, so why not wired phones as well? If you aren't doing anything illegal there's nothing to worry about. If you are plotting to blow up a building or something then I think we have the right to be protected. I think we need more of it, perhaps it would address some of our domestic problems such as drugs, organized crime and government corruption.
What I find pathetic is that there is a person or persons out there that are so politically motivated that they are willing to put the nation's security at risk by leaking classified information just to take a shot at the president. If they truly thought that what Bush was doing was unconstitutional, they should have hired a lawyer (I'm sure the ACLU would have loved to take the case) and fought their fight in court. It is trully gutless just to anonymously tell a reporter.
