As I understand the incident, it did NOT rise to the level of the above. Five guys sitting around a table peacefully eating a meal is NOT such a situation, whether 911 was called or not. There appears to be a need for more training on the part of the cops.
But your understanding is irrelevant.
The police only need a reasonable suspicion, and a frightened woman calling 911 about you is quite enough to investigate you.
It matters not a bit if the woman was completely wrong about you and frightened over nothing.
