The officer had the right to approach him. He might have had some reasonable suspicion to question him, we don’t know. Regardless of that he certainly had the right to ask the guy to take his hand out of his pocket. Not 100% if he could order it, but once the guy refused and started acting so frantically, he certainly has reasonable suspicion and reason to believe the guy might be a danger.
The courts have given the police a great deal of lattitude when if comes to protecting their safety.
Yes we do. It has already been pointed out to you he told the man he stopped randomly.
Again, you're "oversights" seem to have very narratively consistent loci.
And I have personally taken some of it away.
Don't be surprised if you see more.
Did I miss something? What is it that you describe as "acting frantically"?
