The problem is the same as other internet crime. You may live in the U.S. but your bitcoins were stolen from Mt.Gox in Japan by some thugs in Ukraine. The thugs transfered them into a wallet running on a server in Saudi Arabia.
Now, if I go to the local police with that story what is going to happen? Will the cop hop on a plane to the Saudi kingdom? Will he call his contacts in Ukraine, or bone-up on Japanese law? Nope. He/she is going to look you in the eye and say "What the hell are you talking about"?
At least for the next few years we are on our own.
stop talking bullshit.
law enforcement is very clever and has experts when it comes to IT. They even managed to sneak into tor and get the silk road server.
Of course they can investigate about bitcoin theft and might find the thief
when I got ****ed, law enforcement took my information, said thanks and bye.
if you think law enforcement have any ****ing idea how to enforce laws when it comes to bitcoin, you are out to lunch or you are IN law enforcement with considerable strings. simple as that.
