Former US President Jimmy Carter is so convinced the U.S. is monitoring his movements ... he won't send emails when he communicates with foreign leaders.
Carter was angry about what he believes are gross abuses on the part of the NSA ... so he said Sunday on "Meet the Press." It didn't seem theoretical ...he really believes he's being watched.
Carter says he's forced to use snail mail because it's the only want to ensure his privacy.
Let's be honest ... how many 89-year olds know how to email?
