It certainly would be unnecessary. However it would be the law, and if someone was not aware they were within park boundaries and were just doing what was required by law they could be unaware they were signing up for arrest.That would be a moron CCW person who continues to engage the cop AFTER the cop has released him.
It was a simplification.Laughable. Is that you how you think police act and talk? Like robots?
However yes that is often exactly how they act once a boundary has been crossed. When they realize someone commited a crime and is currently armed that is often such a boundary.
Taking someone into custody who is currently armed or potentialy getting into an argument with someone who is armed is risky. Polite mannerisms go away and they are very formal.
I live in sue happy CA, and many of the officers in urban areas act so formal and by the book when they come into official contact with people that they seem very much like robots.
When they casualy mix with the public or take reports they can be a little more social.
Every single word and action they take during a stop that could result in use of force (spray, taser, firearm etc) will be heavily scrutinized in court (recorded by dash cam) if they are sued.
They want to stay safe from both harm and lawsuits, and often sound like a pre-recorded message.
I don't know how they are for you in Michigan.
