Even if TM was the cause of those 750k vanishing, there is no way this was done without anyone noticing it. It would be them stealing their own coins and blame it on TM after.

Also we are to believe that they had no personal data of supposed thief when they were asking an arm and a leg for someone to withdraw large funds.

Furthermore, if they REALLY did not notice because they are so extremely incompetent, then why all this secrecy, instead of providing us with all the information/data required to check for ourselves?
Cold wallets, thief ID (probably stolen).

It just does not add once again, why we are left in the dark if TM really was the reason, or anything else was the reason for the theft.

A liar will try to release as little information as possible, because if he releases information, someone could verify it and possibly detect the lie.

There is either some government involvement possibly blackmailing him or his family,

OR he screwed up badly in trying to trade the BTC in an attempt to pay off liabilities for court cases/licenses etc with customer funds, he believed he would be able to get back easily with fees/arbitrage between exchanges and other ways to abuse exchange powers.
He then got surprised by BTC shooting up to 1200 when he already sold out all the BTC, resulting in him having to retreat into illegal activity in a desperate attempt to regain the funds which would explain why he keeps silent about it.

What we do know is that 160k passed through the MtGox API just recently, which unless there is some other mysterious explanation, is a clear indication that MtGox is in control of at least 160k BTC still.

IF it is not, he would have to explain to us how it is not. Again, he remains silent about it, which makes no sense if this BTC was stolen. It would be in his interest to show us the addresses it was stolen from.

Nothing of what Karpeles does or says makes sense unless you dive into some extreme scenarios which are just more likely as otherwise the puzzle pieces do not connect.

Pure incompetence would not explain why there is all this secrecy about how exactly the coins escaped. Even if they stole them themselves, they could show us the chain of events of the coins escaping.
They are not doing this, because there are some men in black/mafia etc hindering them from doing that OR it would uncover all the fraud involved they were conducting.

If someone wants to bring up a theory which does not involve at least some part of the above, he would have to explain the secrecy of karpeles concerning this case.
He would have to explain why all of the sudden 160k ran through the gox API just recently, which stemmed from the 424k address Karpeles used to prove his exchange was not running a fractional reserve.

I can only repeat that there has to be put pressure on the authorities to interrogate him and squeeze the information out of him, we need to complete the puzzle, one of the most important information being the cold storage wallet addresses the coins were stolen from supposedly.
