I'll be 100% behind you, or anyone else who can help prove that there was any crime committed here.
BUT....
The police will still think we're just complaining that someone stole our secret sword in some abstract WoW world. There is no crime here. There never was. The fact is: if BTC is the same as fiat currency, then we have a case. If it is not, and it is a revolutionary way of holding value and wealth, then the established means of law enforcement is USELESS. Learn your lesson. That is all.

The nearly $400M in bitcoin that MtGox lost sure raised a flag for law enforcement. They might be scratching their heads trying to figure it out, but they know it is a big deal. If I lost coins on an exchange, and I believed fraud was involved, I'd report it to law enforcement even if I thought they would roll their eyes at me. Stealing bitcoins is a crime in almost every jurisdiction. Not reporting it just gives law enforcement an excuse to keep rolling their eyes.
