This is all very nice rhetoric, but its just a perspective. Even you admit that from a pragmatic and realistic perspective that police are different than normal citizens, hell you listed yourself several reasons why in your opinion. Heck you dismiss the high speed cash exactly not by citing law, but by citing that its stupid and reckless in your opinion, not something we are arguing.
All I am saying, is that under the current laws police have special privileges that ordinary citizens do not have. You may not agree with these laws or what police do, but these laws do exist which give police special authorities and powers where ordinary citizens do not have them, that's all I'm saying.
