This is a link to a Reuters article about a young man in the UK being charged for breaking US law, even though he was in the UK when he committed the "crime."

There is something disturbing about the fact that the United States is able to enforce US law in other countries. I did not realize Britain was a US territory. Were I a British citizen, I would be terrified by this possibility: regardless of the laws in my own country, my native sovereignty could be superseded by the rule of a foreign power. Maybe the sun has finally set on the British Empire. God save the Queen.
