This posting is for our US members, but is probably of interest to privacy advocates around the world.
The key legal basis for deep electronic surveillance by US law enforcement and intelligence agencies, justified on the basis of fighting terrorism, is Section 215 of the US PATRIOT Act.

I will not amplify my position here, but suggest you do your own research. In that vein, here are recent articles I recommend:

For ease of writing to your members of Congress, I recommend using Democracy.io a service originally developed by EFF and now maintained by Taskforce.
