100% Scare tactics this isnt even a police issue its more towards copyright. Also its a generic email/letter thats been sent out. Theres no logs of ip address connection time date etc. if there was that would be something to be worried about. Really would be the isp who would be notifying people as they used to do when a customers ip address were seen in a torrent swarm when downloading copyrighted material. Ive received nothing no emails no letters, do you think the police are going to go round to 7,000 peoples houses to confiscate there devices highly unlikely. Imagine how much that would cost in police resource's etc. Its the big fish there after stream sources providers etc. Its just a way of trying to frighten the end users.
