Rebuttal was already posted:
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?
simply defies logic and reason... there is no way they couldn't have known the situation that was brewing underneath them, except for willful blindness and apathy to the problem.
Just inconceivable they didn't notice it.
There was another thread posted, where someone put forth the possibility that while there was a malleability issue, that Gox was trying to use it as a scapegoat to cover for the possibility, that they found they couldn't access their frozen wallet and that their keys weren't working.
I find this much more plausible than some ring of anonymous unverified accounts massively double-withdrawing in the volumes they would have to do to cover that amount of coins in a limited time, without drawing attention to themselves.
It would certainly explain how desperate they sounded a couple weeks ago when they were demanding the bitcoin devs fix the malleability issue asap... they seemed absolutely frantic.
(and if this was the case, soy, you can rest assured, your bitcoin monies are safe and sound at the frozen wallet address, and nobody is going to be able to get to them... not even the people at Gox.)
