So, what's so dangerous about the bill? If it's really designed to protect innocent children from pedophiles, why should anyone (other than pedophiles, of course) be worried about it? As David Seaman pointed out, H.R. 1981 contains some very hefty surveillance provisions, including one which would require ISPs to keep track of the IP addresses it assigns to its users, and to record that information for at least 18 months. Other information like credit card data and who knows what else would also be stored.
Adding insult to injury, the bill describes its target ? in reality the entire internet ? as 'unregistered sex offenders.' Once again, ouch. The scary part is that the bill could lead to monitoring of all internet activity, so that a subpoena can be issued for further investigation of the suspicious activity.
