Big Brother on the Internet?
Found on CNet News on Friday, 28 January 2011
Criminal investigations "are being frustrated" because no law currently exists to force Internet providers to keep track of what their customers are doing, the U.S. Department of Justice told Congress.
"The problem of investigations being stymied by a lack of data retention is growing worse."
A long data retention won't really help police much; criminals will simply hide better (than most already do) and it will tempt the government to snoop on its citizens online behaviour.
