I can speak from experience here, as I've done many car stops of stolen vehicles. And I hate to Monday Morning quarterback these situations. But when you pull over a car that "pops" stolen on the computer, and get the guy pulled over, my gun was always out and in my hand. The driver (and passengers, do NOT get to stand around like that). They are pulled out at gunpoint and searched (frisk) for weapons. I don't care about an ounce of pot, just weapons. Preferably cuffed first. Yes, you can cuff a person in this situation, even if the car turns out NOT to be really stolen; IE, a computer glitch, or it WAS stolen and returned and the "stolen" status was never changed. Assume nothing. You can uncuff later, if need be.
Guns pointed at everyone in that car. That gets the message across, that even if you ATTEMPT to pull a gun, you are going to be "lit up". Lit up meaning shot full of holes. This young officer, the little I saw, was looking down, at whatever. You NEVER take your eyes off the guy. Then it seemed the rookie froze, when he should have been unloading an entire magazine in to the perp.
I listened to the radio chatter, and he didn't seem to put over the air the gravity of the situation. Another officer asks, "who we looking for?", meaning no description was put over. Bad. That's one of the first things you do.
Put a description over, pick up your partner and throw him in the car and haul tail to the nearest trauma hospital, assuming EMS may be too long in arriving, and the hospital is closer. Being hit in the armpit means the bullet can go ANYWHERE in your body.
My .02 cents.
