x2! Lets see, what good did the person who got capped think was going to happen? Hrmm, NOTHING MAYBE? If you pull over with another driver, you are obviously trying to start shit. Especially if you have kids in the car, you gotta be a sh1tbag yourself to pull over and "exchange words" which might endanger your kids.
The now dead victim could have threatened to kill the shooter driving the Civic, then the Civic driver did something about it. We have no idea...
