Ummm, they held a PRESS CONFERENCE to release the findings. It’s not a confidential matter. Way to disprove your own point.
Didn’t they just say that the investigation was ongoing? That this was a preliminary report? Aren’t ongoing investigations confidential?
Police routinely give press conferences to update the public on ONGOING investigations. They don’t let investigators sell books about the results of ongoing investigations.
Secondly, show me where Sheriff Joe gave his official permission to use the information for a book. After all, supposedly he provided the resources for the investigation - the results belong to him.
