I believe that I answered you regarding Bitcoinica transactions in the Blockchain - it's pointless, because there's virtually now way now for me to prove that the money went TO Bitcoinica (I can prove that the FROM address belongs to me, but I could just send it to another address of mine if I were malicious)
Blockchain analysis together with other known Bitcoinica transfers should give a good indication as to whether the transfers were indeed Bitcoinica related or not.
Since there's no reason not to publish the transactions, I find it strange that you claim it's pointless instead of simply doing it.
As for what's good for Bitcoin; I'd say Bitcoin scammers behind bars. That would be excellent in deterring future scams.
That seems like a stupid idea. Not only would it not deter others from scamming (they'd just need to avoid publishing their details to scam without risk), you'd actually deter others who made stupid mistakes like this one from coming forward and attempting to fix their mistakes.
Now apply your reasoning to non-Bitcoin crimes, like burglary.
