> You have to know there is such thing as TOR exists & see first part of the comment. I would suggest that anyone who is in the business of identifying people based on their IP, especially for criminal matters, should be aware of Tor. Doesn't have to be every beat cop, but whatever process allows a police officer to turn "this is the IP address the suspect used" into "this is an address/person associated with that IP address" should have "Be Aware - this IP address is the endpoint of an anonymizing service and so there's really no way to associate it to a single person." Kinda like how if you are given a physical address and it turns out to be a public park or something, you think, "Oh, this is different in kind than a private house" rather than just finding whoever happens to be standing in the park and taking them down to the station for questioning.
