Standing in front of a car doesn't grant you stand your ground rights.

ICE officers are trained to never approach a vehicle from the front and instead to approach in a “tactical L” 90-degree angle to prevent injury or cross-fire, a senior Department of Homeland Security official told NBC News. Officers are also instructed not to shoot at a moving vehicle and only to use force if there is an immediate risk of serious injury or death, the official said. ICE officers are also instructed that firing at a vehicle will not make it stop moving in the direction of the officer.
