When an armed porn raid took place *at the wrong physical address*
apparently based solely on ISP information derived from an IP
address, the results could have been deadly. It appears that a
dynamic IP address was incorrectly mapped to a subscriber.

We've seen cases before where apparently nonsensical raids have been
conducted for the MPAA based on IP addresses that may well have been
incorrect.

This isn't funny anymore, if it ever was. ISPs, search engines, and
other sources of retained Internet user activity data are being
treated as adjuncts of law enforcement, with the incredibly
dangerous and faulty presumption that such data will always be
accurate and reliable.

In these kinds of situations, such errors involving retained data
could get people killed.
