Whether he is a nice kid or an asshole has nothing to do with how laws against revealing his identity apply.
Being a victim doesn't give you any particular rights to publish this information. But the law says nothing about merely telling it to all your friends. And if you're walking the line between these two, it's probably better to talk to a lawyer before speaking.

It's a fine line between crime and entrapment, so when your business depends on having these crimes happen to you then you should be extra careful in how you go about dealing with the perps identities, especially if they are minors.
