On Thursday, Congress is set to begin consideration of H.R. 3523, the "Cyber Intelligence Sharing and Protection Act of 2011" (CISPA).
CISPA, also supported by Facebook and Twitter, would encourage companies to give the federal government sensitive information that is now currently prohibited by law without a warrant or subpoena.
CISPA was also written in broad enough fashion to potentially override every existing privacy law due to a "notwithstanding provision in law" clause
. . . especially if you are an online purchaser of ammo or firearms-related items.
