The problem is the police really don't care what you think your rights are anymore. They're all about shaved heads and intimidation. They're out of control. God forbid you be in "contempt of cop". They don't like people who ask questions.
There of course some dicks, but where I live if you are respectful you will be treated with respect. The way I look at it is I wouldn't want a job where I had to wear a gun to work everyday. I will preface that with I graduated high school with several people that are now cops. I just am up front with them and tell them that when you have my driver's license in your hand I assume that I am under arrest, and I won't answer any questions.
It's obvious to me that no disrespect should be shown, but respect is earned and from experience I consider all cops to be vile until proven otherwise. It's a self defense mechanism born from years of bad experiences with bent cops.
It is obvious that all cops aren't scumbags, but at what point did they decide that shaving their heads was a good idea?
