The US have done this a lot, luring “hackers” and other criminals to the US and then arresting them.
However, if I'm going to break one of their laws that they feel very strongly about, I'm probably not going to travel to the UK. That's just begging for something bad to happen. Why risk it?
So in this case, if you know the US is looking for you, why, oh why, would you travel to the US?
