no, the USG was way up his ass in many ways. not to mention the $5.1 M they seized from Tibanne here in the US. i'm sure he was under a gag order. so was the Japanese police ever since the 17.5 to 0.0101 hack as he reported it to them.
i'm sure during the subsequent investigations his systems got compromised. and if i'm right, that they had access to the systems, i wouldn't put it past the gvts to steal coins that could be responsible for the depressed prices we see today in the never ending inexplicable selloffs we've been getting. that's my tinfoil.
The June 2011 hack happened exactly as it had to. With access to a huge amount of coins the price had to be dropped to near nothing, allowing a certain dollar value of btc to leave the system. A non-state actor would face it the same way.
I'm definitely not ruling out your theory. Just feel there are other possibilities.
