Yes, it's time to let it expire.
Unfortunately, the financial provisions that were on the police state wish list since day one and opportunistically trotted out on 9/12 don't expire. Only a repeal of the permanent provisions will get rid of them. Don't hold your breath.
As long as the threat level is "elevated" it should be obvious that we'll have to give up a few civil liberties in the interest of safety. When the threat of terrorism is gone, and we're back at 'green', then sure, we can get our freedoms back.
Until then, well, this is a different world, after all.
I'm sure the Departement of Homeland Security wil let us know when it's safe to be free again.
Until then, we should all keep our mouths shut and thank our DHS overlords for doing so much to keep our beloved Democracy Free! Er, um, Free once the Evildoers are caught and brough to Justice! Well, not exactly Justice, but a secret military tribunal.
THEN we'll have Freedom!!!
