I think this law should be compared to the courts prohibiting the release of the personal information of those who were involved in animal experiments at OHSU a few years back.  When prohibiting release is clearly to prevent injury or worse by those who have more passion for a 'cause' than inhibitions, it is justified.  I would oppose a blanket prohibition for police officers in fatal incidents, however.  The public does have the right to know if this is the first or the fourth time an officer has used deadly physical force.
