During a murder investigation, a suspect is posting incriminating messages to Facebook groups. He's using net cafés around the city. How difficult would it be for the police to track the IPs? Would they need cooperation of the California police (I think that's where Facebook is based?) to get the IPs, or is there a simpler way? How long would it be likely to take? (this
case study helped, but it's between UK/Norway/Spain.)
Secondly, am I right in thinking that machines in internet cafés have static IPs, so that the police would know which specific machine had been used?
This guy is coming and going with a reasonably large group of gamers (making them all suspects). In one of these places, the owner is in the habit of tinkering with his computers and switching out parts. He's not particularly careful about putting the towers back in the same numbered stations from which he took them. Could this cause confusion if the police tracked the IP to a particular machine, which is now in a different place than it was when the crime was committed? (As in, they'd suspect the guy who was using Computer 3 that night based on the IP, not realising that the machine which is now Computer 3 was previously Computer 16?)
