Obviously you have never worked the streets. The big mouth is the one who instigates. If it is causing a problem, it has to go before you can assume control. I think your assumption that all of the public is anti police. I have to believe the vast majority has respect for officers who respect themselves and th public. Too, I believe 99.99% of the officers are there to "serve". They certainly do not "loathe the people they are supposed to serve".
I think your assumption is that everyone the officer comes into contact is a villain of some sort. The vast majority of police work is community relations and answering legitimate complaints that good people want to report and get a solution to the problem they are having. Of course some of the people they come into contact are hardened criminals and those people are treated differently than some old grandmother whose cat is missing or the teen neighbor is playing music too loud late at night.
Now if you want to arm every person with a badge a camera and recorder and arm every vehicle the same way, the cost to taxpayers is going to jump substantially. Your PR work is going to go to hell as soon as your perspective informant sees the recording device. The people who are just trying to help do not want to become part of a trial and have someone chasing them because they are "squealing". Police work is common sense. Officer is operating at his own discretion. How can he extract the most and best info. Just like in the movies - let a thief run free if he can tell you who is committing armed robbery. Common sense and the most value.
You see everything with officers eyes. Your bias is from your life experience. I understand where you are coming from but I disagree about cameras. Cameras will save lives and money.
I watched, like many other people, the officer kill the guy in SC for not complying and them walk over and throw the tazer gun down like the man had taken it. It was cold blooded murder and if there was no one filming the officer would have gotten away with it. This kind of thing has happened so many times and its no coincidence that now we are seeing so many cases brought to light. Its because people are filming every time they see police.
You proved in your own words exactly how so many officers think, they want to do what ever it takes to shut the " Big mouth " up. And I believe you when you say whatever it takes.
I have heard my brother and his officer friends sit around and laugh about the things they have done, things that would get them fired in a heart beat if on film. They all to a man have an underlying contempt for the rest of society. You have it. You can sense it what you've written and how you've written it. I'm sure you will disagree.
The thing is this, I get it. I know why most all police I know tend to have mostly other police as friends. Its a career that forces most officers into a us against them mentality. There is no answers to solve all of the ills in society as there are no answers to the dissolving relationship between citizens and the police force that is there to protect them.
However, the studies show that those forces that have implemented body cameras have shown a great decrease in instances of police misconduct and a marked increase in expedition of judicial process.
