OK, I'll bite.

What are these "protection from abuse" measures which are available to citizens and foreigners under this Act, or other US law?

Donuel? DougR? WYSIWYG? KimC? Norton1? Celtic Soul?

Can any of you tell us what legal protections we have to prevent the past abuses by the US government against ordinary citizens, which are now legendary not only in the US, but around the world?

We're waiting...
