However, the first thing a cop needs to know when he arrives at one of the drunken brawls is WHO are they dealing with.

Nothing in the facts of this case suggest there was a "drunken brawl." If that were the case, then LEO could have simply placed him under arrest for disorderly conduct, without first asking to see ID.

Those who try and expand a simple request for id into a huge example of tyranny run amuck have little credibility among conservatives. Now Leftists do this sort of thing all the time.

Presumably you believe cops are well trained in mindreading since they are expected to know all instantly upon being called to a incident.
