In the story above, a motorcyclist drew his weapon when a road rage [intentionally] bumped his Gold Wing trike, and then approached him aggressively. The only time you can use or threaten to use deadly force: when someone poses an imminent, credible threat of death or grievous bodily harm. Someone walking towards you, swearing, does not in and of itself constitute a deadly threat. “You’d end up killing all sorts of people if that were the case,” TTAG’s Jon Wayne Taylor points out. If, however, the man is screaming “I’m going to kill you” and has the means to do that (fists count), well, that’s a different story. But not this one.
