It might matter as to how you came into possession of the report. If you are legally permitted to have it, I would think you can do with it what you will.
However, if you post the entire report on-line, and something should happen to one of the named parties (ID theft, assault, etc.) and it can be traced back to that exposure, you could find yourself at the receiving end of a nasty civil suit.
Why would you want to post the entire thing on-line?
If you do, I would STRONGLY recommend redacting (blacking out) any potentially critical identifying information such as last names, addresses, birthdates, etc. And I would avoid publishing the names of any juveniles if I were you.
However, the best bet would be for you to consult a local attorney before taking this action ... it's better to be safe than sorry.
