You'd be guilty of thoughtcrime. As was the judicial nominee who was asked if he was now or had ever been a member of a Constitutionalist organization.
Conservative thought WILL be criminalized if the left gets their way.
I'm a terrorist plotting my activities in America and I know this has been enacted. Here's what I do.
1. Communicate from public hot spots. Whether a McDonald's, Starbucks or public park with Wi-Fi access.
2. I use municipal provided Wi-Fi from a laptop by going to out of the way places. You know we'll have to start looking for guys using laptops in dark alleys.
3. I rent an apartment in a multi-unit dwelling and look for unsecured connections in my building never having subscribed to an ISP.
Those three scenarios alone make it 100% impossible for this to be an effective law enforcement or intelligence tool. There are way too many ways to access the internet on shared connections.
I didn't even start on using libraries, Kinko's/FedEx stores wired connections where public internet access is possible on a wired connection.
As much as I would like to see government have tools to track would be terrorists this has more problems than solutions.
Or if Hillary gets elected.
