This is a title
Is _ANYONE_ surprised that a federal LEO of the USA believes in their right to remove a person's, or organisations, property without giving them a change to defend themselves?
In the free world this sort of behaviour is usually called theft.
It's not even going to matter if the (former) holders of this property are operating legally in the jurisdiction that they're based in. Now who can these victims appeal to for redress?
No one.
Even if there was a world court, and the USA had signed up to be bound by that courts judgments, they would ignore such irrelevancies. See the WTO for precedents.
Perhaps now really is the time to end this _special_ relationship between the US & UK. Maybe then the UK would regain some of its former standing in the international communities.
