Have a lot of encounters with law enforcement do you Flat man? I am not suggesting any thing this is what I said.
No matter how minor the law was, in every case the person that broke that law, with their actions, attitude and refusal to comply with a lawful order and becoming combative and resisting arrest brought on the reactions of the officer and they got what they deserved. What ever happened they brought it on themselves.
It is not the minor infraction that gets them killed it is the disobedience, the unwillingness to comply and cooperate and the rest of their stupid acts that get them killed.
Do you encounter a lot of police officers that "acts out?" maybe you should stop doing what ever it is that gets the attention of the police. How is it that you have witnessed cops yelling at people?
How do you expect to respect the person in the uniform when you don't get a chance to know them. If you respect the uniform you may find that the person wearing it deserves your respect.
as long as there are people like you things will never improve.
