I kindly request that you show the pointless transaction details and that you own indeed the from address as you mention. And from my humble understanding of bitcoin, it should be very possible to prove the beneficiary was bitcoinica, not even mentionning the über talented people on this forum which will make it very clear.

Even if you were malicious, you cannot redo the past transactions to suit some kind of show now.

Considering your statement of willing to make things right, it is extremely pertinent and relevant to respond with actions and put the light on and alleviate further concerns.
