...and tells him to get the **** off the road. So, instead of complying with the officer's direction, hoping that by being passive the cop continues to drive on, he gets belligerent, causing the cop to turn around and come after him.
Doesn't sound so plausible to me.
If he was concerned that the cop was going to id him, why create a scene? Wouldn't it have been better to just apologize and get off the road, and not give the cop a reason to come after him?
I probably said this 20 pages ago but a good way to confuse yourself about any situation is to assume it occurred in a world in which human beings always act logically.
If Brown's judgment sucked as much as mine did when I was 18, then who knows what he did. That goes both ways - it's not like bad officer-involved shootings are purely in the realm of science fiction. They absolutely happen, for a whole spectrum of reasons.
I suspect there are JFK assassination threads on this very forum that have gone exactly the same way. "But if Oswald was really the shooter, why didn't he have a brilliant escape plan organized in advance?" Maybe because he was kind of dumb? Because humans rarely show perfect judgment or even a keen sense of self-preservation?
Indeed, otherwise police would never accidentally catch serious criminals when stopping them for minor traffic violations. There has been at least one study (CBA to google) showing that serious criminals are more likely to commit such obvious minor traffic crimes than the general population.
Short-term thinking often trumps longer term thinking. "I want to get away from this cop, now" as opposed to "if I do run away, it will look odd". People sometimes panic and make stupid decisions.
