Concerns about CISPA cyber security bill spread

A growing number of lawmakers are expressing concern over the controversial Cyber Intelligence Sharing and Protection Act (CISPA) bill that's scheduled for a vote later this week in the U.S. House of Representatives. Backers say the bill aims to improve Internet security by making it easier for Internet Service Providers and Internet companies such as Google and Facebook to collect and share a wide range of user data with government security agencies. Privacy and civil rights groups, and even the White House have criticized the bill, contending that it oversteps existing privacy laws and its passage would enable widespread surveillance of all online activities under the pretext of cyber security.
