Nah, the second shot probably wouldn't come as the smart cop would be dropping down, if not knocked down and the perp would take a few seconds to re-aim, while you pull your own weapon or roll towards the back of the car. That is, if he didn't start driving away, thinking he had gotten you and if his own face wasn't cut to ribbons by the glass. Remember safety glass makes many small cuts, it just doesn't cut a vein or artery open like plate glass shards can.
