Stories like this have been around for a long time. I think the cops' words were almost universally trusted generations ago. Thanks to modern technology, however, we are starting to see the other side of it.
Cops are also like a fraternity with an us vs them. I believe they will help to cover up for each other. That can be good, but it is mostly bad. We have several prior or current police officers on here. How many of you will discuss the unofficial policy of " if you run, then you will get beat" to other people? Even today that still gets covered up. I've known officers that left the force because of that. I wish they had stayed and tried to fix it instead, but I can understand their thought process.
