Yawn. I remember during the Clinton administration, how he wanted just about every financial transaction to be reported to the government, a "clipper chip" in every computer to let the FBI have a backdoor for domestic spying, and more government snooping on anyone legally owning a gun. The argument was that if you snoop on millions of people, eventually you will find a criminal. Most leftists were delighted with that. Now there is a net narrowly focussed on terrorists and their helpers and you would think it is the end of the world and the leftists want to grant civil rights to foreign terrorists.
The valid argument the liberals have is "Two words: President Hillary." I find it scary, because the conservatives may focus on terrorists, but President Hillary? Who are her enemies?
