The US Government does not acknowledge the presence of bitcoins... They would probably help you if someone robbed you in person or hacked you...
The FBI, CIA, Federal Reserve and the Department of Treasury, Department of Homeland Security and Department of Justice all have extensive knowledge of bitcoin. The recent FinCEN guidance, and DOJ/DHS action against MT GOX and it US subsidiary Mutum Sigillum make this clear and possibly indicate additional regulation and legislation coming.
A simple "STFU" would have sufficed
