The Feds recently subpoened Mt.Gox to force them to retain trading records, so the chain of ownership will be known to law enforcement.
You think it's a given that MtGox has detailed, accurate and long term trading records? From a company that managed to lose all but 2000BTC out of 750,000BTC (if the story is true) before they noticed and pulled the plug?
Transaction records they probably have. Posing as upholding an ideal of secrecy they may be less than helpful to investigators though with that much money gone they probably should, help that is.
Agreed it's odd it took so long to interrupt the outflow/loss. They must have been out of the office. I wonder how long it took to empty SR2 using the same technique.
The theft aside, I wonder how many complaints they had about double-spending/double-sending due to lousy website software. I can see how that could be costly. Maybe they tried to placate some users by reimbursing loss due to a double-send that resulted from the lousy website software but that would not have been any kind of an automatic refund and perhaps they hoped to cajole the recipients of the double-sends to return the Bitcoins.
Interesting article earlier today comparing early Paypal experiences/ripoffs to MtGox difficulties.
And my first use of mid-1990's banking software which somehow managed to wipe out my hard drive. I note the banks got better at it. Why didn't MtGox effectively spend more money on software/hardware? Hundreds of millions of dollars entrusted to them and they didn't keep up the infrastructure? Bet money was readily spent on best travel, best hotels and the like.
