Can you be more precise about where you saw someone attack or attempt to attack his physical person?

If you're referring to the "DieJakeDie" account, I acknowledge that it existed, but it was very clear that it had no involvement with victims or (as far as anyone can tell) anyone involved in the Tor community. The integrity of the Tor process was not compromised by its existence, any more than the integrity of a government trial is compromised by protesters outside calling for blood.
