You misunderstand wiretap vs. intercepts. The only targets being monitored are ones who were intercepted getting calls from known terrorist. That makes them foreign Agents. The NSA does not have the time and the resources to wiretap every American. The average paranoid schitzo out there has nothing to worry about, except when to take their meds.
If you read the laws concerning the Plame case there was no laws broken. The only thing Fitzgerald could charge Libby with is lying to a Grand jury.
However, the person(s) who have been leaking the wiretap story is a lawbreaker and severely damaged the NSA's ability to do their job of protecting this country from a foreign threat.
This is my point--we've already learned that Quaker groups have been watched (http://rawstory.com/news/2005/National_Security_Agency_spied_on_Baltimore_0110.html), so I do not believe this to only be foreign agents. That's abuse. I am aware Libby was only charged with lying to the Grand Jury, much like Clinton was. Don't tell me you think the Clinton indictment was valid and the Libby one not?
Ultimately, I'm not convinced this leak of the NSA program has "severely damaged their ability to to their job." Do you have proof?
