Last year during a Black Lives Matter rally five police officers were murdered. The president should support the police and give them respect. They have a tough job.
The other day President Trump lighted the exterior of the White House in blue to express his solidarity with the police.
If you have an encounter wIth the police address the officer as “Officer” or “Sir” or maybe even “Mam” though I have not tried that. In doing so you will have established respect. More importantly you will have the full force of the constitution on your side.
To go into an encounter with the police with an negative attitude doesn’t help anyone. I am truly surprised that the police are so tolerant these days.
Of course all lives matter. The only difference between black and blue is ue and ak.
