Meaning what?

While investors going after Kerviel, they're not going after the management ultimately responsible for the loss due to a guilty lack of competence with a trading desk management at least lazy and amasingly not very curious(Kerviel get caught , we'll look stupid but off the woods, he makes a lot, we get the credit and the bonuses, the guy being a small shot)?

Was a crime committed?

If so, the bank committed it, it should be probed and trialed not just the trader? Was it against the law to build a 50 billions position?

Has Kerviel broken the law by doing so?

By doing so he caused a major loss endangering the bank without the management authorisation(good he wasn't) they say, the management should have known better and end the experience sooner?

Still not a criminal case, whether he acted on the management's behalf or not, I see no crime? His actions engaged the bank in losing trades, a trading desk management problem that let it happen.

If a crime had been committed, shouldn't the state go after the bank, the management and Kerviel to be trialed and the jury to decide who is guily?
