A county sheriff in Florida has a problem. Every time he gets close to identifying the suspected child predator behind an anonymous Internet profile, the Internet service provider tips off the suspect.

“You have a sex predator say that’s using a certain IP address to contact minors, maybe entice them,” Rep. Ron DeSantis told the Washington Examiner. “You can subpoena that and get that information. But what happens is that the Internet service provider that provides the information will then turn around immediately and will let the suspected predator know that that IP address, for example, has been requested by law enforcement.”
