An online petition crated by Mozilla, the Electronic Frontier Foundation, Reddit, and the ACLU (among others) to register concern to the Obama Administration over the recent revelations regarding government surveillance.
I would strongly recommend you check out (and if you agree, sign) the petition.
As a society we cannot afford to simply allow our civil liberties to slip away from us, even if for what appears to be a good cause. Out founding fathers very wisely build our government on a firmament of checks and balances. We are in deadly danger of allowing those checks and balances to be swept away, to all of our detriment.
