Browse the mainstream coverage of anything related to gun control. It will be hard to find anything skeptical of police and their special gun privileges and exceptions to gun control.

There may be a nearby article about police brutality, negligence, incompetence, corruption, favortism, or even murder. The article may even suggest that the problems are sustemic in some departments.

But as far as the media can tell, they are completely unrelated topics. It's just assumed that gun control excludes police, and that's obvious and normal and right.
