Wow... where is the option to vote the summary and TFA as troll?
Seriously. They full of misrepresentation (CoLP is just another area force like all the others in the UK. CoLP is NOT a private force. The fact that corporations vote in CoL is irrelevant here as voters have no direct influence on the force - policy comes from national level. CoLP are national specialists on this kind of 'soft' crime and are the force responsible for national level investigations of this type. Seizures would have needed to have been court sanctioned/ordered and as is often the case with ongoing investigations where the details would be sealed until said investigation was completed. The fact that large scale copyright infringement is a crime was made by the elected national government and not by the CoLP.)
Wilfully continuing to aid criminals after you are aware of providing such aid (except on threat of personal safety) is in itself a crime in the UK.
ICANN etc have operations in the UK and are therefore have legal responsibility/requirement to comply with such court orders in the country they operate in. This is identical to the many cases where a USA court orders extradition for some minor thing on a non US company director just because they have a sales/import office with 5 staff at some container port in Florida.
