The wiretapping is so wrong, on every level. There is no doubt about it. When we take our personal freedoms for granted we all lose. Absolute power corrupts absolutely. Just because some says they are Chrsitan doesn't mean that they can't do wrong or evil, just look at the Bible.
Please, "NOTHING TO HIDE", I absolutely "see red"when I read that and realize that somebody has written it with a straight face. It is the most ridiculous statement ever. You really must get away from that mentality and realize that you don't have to account to the government for everything you do, they have to account to you!
Gee, I know I DO HAVE something to hide,
it is called "privacy".
Anyway, to get to your other point: If these wiretaps are truly ONLY on overseas calls from America to known terrorists. The government should have no trouble at all getting a warrant to intercept and eavesdrop. The legislation, unfortunately, doesn't limited eavesdropping to "overseas calls etc." If this was ONLY what the government wanted, the legislation would say so.
