I know, I know there could be a million fire and police jokes made about this, but give it a minute to think about it.
1.) Is there any significance to the ground fire at the front of the vehicle?
2.) What other hazards might be found in this vehicle as opposed to others?
3.) What is the difference in ammunition not in the weapon, vs. a loaded firearm?
4.) In This case the vehicle is unoccupied. Supposed it was occupied with a prisoner locked in the back?
5.) What is the attack method and plan?
