I think a lot of what NW refers to is a product of the Internet. There are, however, still print journalists interested in facts. The problem with reporting on police activity has fallen largely in the lap of the agencies themselves. They are not interested in releasing information despite open records laws and it becomes a tug of war between journalists and law enforcement.
I agree, and I think that the fact that even the Sheriff was willing to admit error in this case speaks volumes. We have seen much more serious incidents involving the death of young men/women where the police have not been as willing to admit error.
