Remember, ignorance of the law is not a defense, and these officers should be held to that same standard.
Agreed. That is a knife that should cut both ways.
LEOs should be the example and obey all the laws, cellphone use, seat belt laws, speed laws, etc.
At the very least, they should face suspension and re-training, up to fines, and loss of their job or even loss of their certification to be a police officer when they break the law when citing or arresting people.
Prosecutors and Judges should have the same strict standards and stop prosecutions when there is no point to them.
