Let's consider the ramifications of this: The FBI steps up the monitoring of law abiding citizens and great expense to private industry. Criminals, terrorists and other evildoers think about and say, "Hmmm......since the FBI might monitor the email that passes through our ISP, let's set up our own mail servers outside of our ISP and communicate directly over VPN's and encrypted P2P networks. Yeah that should work. Or gosh, let's use off shore email serves set up by our own criminal networks posing as legitimate businesses. Or let's set up an little ISP and have some out of band email servers who's traffic can't be spied on." "Those who would trade freedom for security will wind up with neither." I forget who said it and I don't feel like looking it up.
