A division of the DHS has called the ACLU a terrorist organization. As of today, this means right next to nothing, as I notice no one is being arrested or anything. Rhetoric is cheap. To get an arrest warrant, you have to make a generous campaign contribution, at least to the judge.
In the future, everybody will become famous for 15 minutes. The DHS will put your picture up in the Post Office, declaring you to be a terrorist, and 15 minutes later, when you are picked up, your picture will be replaced by the next "celebrity".
