The police were in hot pursuit of a robbery suspect.

Or so they said. I know the California courts and the police here. They are not always the heroes they are billed to be.

Well, really the hot pursuit doesn't matter (although the guy was seen entering the alley and was pointed out by a passerby) because while standing in a public place where they had the right to be, the police heard screaming and fighting.

That's an articulable suspicion if not probable cause, right there. Never mind the hot pursuit.
