Bernie Goetz - acquitted killer and a drug dealer - is more likely to have been part of the swarm rather than part of the solution.
Bernie Goetz has been remembered for what he thought he did, not what he really did.
The version of the incident which stuck in the public mind was a Charles Bronson fantasy scenario, which Bernie cooked up in the days before he turned himself in. He had a detailed, second by second narrative, in which he assessed his situation, made a careful battle plan of who to shoot first in order to escape a situation in which he was outnumbered 5 to 1. This went all the way to his scripted lines. Nothing like that really happened.
The forensic evidence shows a different story. Bernie was in a blind panic, overcome by fear, and firing wild. It's not really clear why he started shooting, because we only have his recollections of it all.
