Depends, have to see the damage to the cop and the forensics. If he gets shot at or close to the car during or after engaging in an assault on the cop, then he deserves everything he got. If he was actively fleeing, that might be a different matter. Also, cops are allowed to shoot a fleeing man if they believe that the perpetrator will or has committed a violent felony, if the kid assaulted the cop, it could certainly fall under that.
