Man threatens people at site of Bourke St attacks

So, a man, whose face the media will blot out for reasons unknown, has gone around Bourke St threatening people.

Apparently he hasn't been caught, so why would the media want to protect the identity of the man the police are looking for?

Also, where's the physical description of the man?  Oh wait, he doesn't look white, so that must be why.

Forget I said anything.
