Another thought on the subject:
Cops work with two categories of people and two categories only:
1) Those that make difficulties either for themselves or for others.
2) Those that are having difficulties: ie victims or people in need of other kinds of assistance.
It's one or the other. It could be argued, I suppose, that a person could be in both categories simultaneously, but ultimately the cop has to decide if the person is a threat that must be dealt with accordingly or a person must be aided in some way.
Once a cop determines how he/she must proceed, decisions are made and if directives are given, those directives must be followed, period. If they're not followed, depending on the threat, the cop has the full force of the entire police department, other law enforcement departments (sheriff, state patrol, federal enforcement, etc) if necessary.
Here's a key point in this regard: If directives are given, they're NOT suggestions and they're NOT directives that can be followed on the individual's own timeline. They're directives that, if not complied with immediately can be met with force of some kind. You would therefore never see a scenario like the following if a person was sitting on the lawn in front of their house drunk and yelling obscenities repeatedly and loudly:
Cop: "Sir, you need to either go back in your house or we will take you in the police car to detox. If you need us to help you into your house, we will."
Person: "I'll go back in when I'M ready. First I want to tell you a story about when I was a kid."
Cop: "Sir, do you need us to help you into your house? Yes or no."
Person: "Listen to me. Have you ever been in love?"
Dispatch: "Officer Smith. What is your 20 (location)? You're needed at the station."
Cop: "This is Officer Smith. I'm going to be here awhile. I've asked an intoxicated gentleman to go back into his home and he wants to tell me stories."
Dispatch: "How long will that take??"
Cop: "I'm not sure. He hasn't told me that......"
Would NEVER happen. The reality would be: Assessment - Directive given - If not followed, then a response on part of cop/cops to force compliance, period.
