Yes his intention is silly because he thinks the "thief" will go to jail. But I am interested for this to go to court and see what arguments Vitalik can throw in the court and what counter arguments the "thief" will make in his defense. The "thief" will have the upper hand I predict because he really did not "steal". He used what code was in the contract to transfer funds in his control. He found a legal loop hole.

Do you ever wonder why Vitalik is not after the "hacker"? Because he and the slock.it developers know they have messed up and they cannot go after him and take him to court. They will lose.
