Richard O'Dwyer is a 24 year old British student at Sheffield Hallam University in the UK. He is facing extradition to the USA and up to ten years in prison, for creating a website – TVShack.net – which linked (similar to a search-engine) to places to watch TV and movies online.
O'Dwyer is not a US citizen, he's lived in the UK all his life, his site was not hosted there, and most of his users were not from the US.
When operating his site, Richard O'Dwyer always did his best to play by the rules: on the few occasions he received requests to remove content from copyright holders, he complied. His site hosted links, not copyrighted content, and these were submitted by users.
