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.
If it violates my Rights, damn straight it matters. It matters a LOT.
Sorry, but no. There have already been cases lost by the cops for exactly the same behavior.
"It matters not a bit if the woman was completely wrong about you and frightened over nothing."
When the cops showed up and saw five guys sitting around a table, they HAD "investigated";, their reasons for FURTHER investigation disappeared. "Asking for ID"; was and is simply harassment.
