If this whole affair is really about terrorists, then enact legislation that states no American can be prosecuted for any crime based upon any evidence obtained from the NSA. So if ANYTHING is handed to the Justice Department, SEC, CFTC, or IRS, then a citizen shall be ABSOLUTELY IMMUNE from civil or criminal prosecution.
This would be a simple solution. They listen to a phone call and call the IRS, you cannot be prosecuted civilly or criminally – you get ABSOLUTE IMMUNITY just as government prosecutors get from prosecuting innocent people.
END of debate.
