Timing is everything, it appeared that, that was his first opportunity to pull out his gun. There is no training for that, paitience is the key to our survival, too soon he/she sees you reaching you're dead, too late you're dead.
How is this guy out on the street with 3 other car-jacking incidents anyhow?

Generally a car-jacking invoves a gun and the threat of death if you do not comply. Isn't car-jacking a charge in itself that carries a hefty sentence? I guess if you commit those things before you turn 19 they will let you go free until you get killed or make goood on your threats.
Man this is a long wait to earn the right to protect myself in public...
