It’s a desire for full and complete transparency from our government, specifically law enforcement.
It has nothing to do with “gory details.”
Privacy is one thing, and it is maintained in private matters that don’t involve the public interest. For instance, I can’t request an autopsy report of someone who isn’t related to me. When a crime like this occurs, the public demands answers, as this affected the public at large.
It is the duty of public officials to provide these answers in due course, and as the investigation allows. It is important to understand what happened, how it happened, and why it happened.
That requires details.
