Am I Wanted By the American Government?

I have just sent this email to the Aerican Embassy in London.
Yo Yanks!
I know you are fond of bombing people and extraditing people to the US for things they have done which are not illegal in their own country. I want to know if there is some stupid and obscure American law which I have violated in my ignorance which could one day result in my being locked up in an American prison for the rest of my life.
Please reply as soon as possible.
