From the generic Stupid MFers thread: In the middle of a running road rage incident, one driver opens fire, hitting an occupant in the other. Naturally, retaliation in kind ensues.
Allison told investigators that he just wanted to “get out of the whole scenario,” which is why he fired the shot.
Obviously the very first thought being “the way to get out of a threat situation is to use my firearm to make the other person back off in fear for their lives” as opposed to simply disengaging from the vehicular dogfight by being the one who backs off first.
