No, it is OUR bounty. Roger Ver is just doing the escrow service, because he is a well respected and neutral member of the bitcoin community and as a proof that the coins will really be paid.
I also recommend everybody to please contact Roger directly for technicalities like bounty payouts.
But why are you all talking so theoretically. In case you really have some useful information about his identity, then you should also know in which jurisdiction he is located and you can easily see via google if this would be convicted or not. The blockchain timestamp is just to prove that you had the evidence first.
In case you dont even know the jurisdiction, then I would assume that you have anything.
But seriously, what do you have to lose. The important part is just to prove the identity. If you HAVE it why should you not make it public in the blockchain and see what happens, why should he not be convicted? In case he is a minor or whatever I am sure Roger would still count this as a full finding. Someone else will take care of him in a different way, I am sure about that, if not his mum. :-)
