I don’t know the backstory to this one. The aggressor has a South African accent and claims the security guard pepper sprayed his kid. Other than that I got nothing. Save this: the security guard did the right thing by using the van as a blocking device. I used this same technique to avoid getting hit by an RPG once. (Brian! Give me back my damn keyboard!) This is a particularly useful technique when . . .
you’re in a parking lot, about to get into your car and a bad guy is approaching. You don’t have enough time to enter the car, lock the doors, start up the vehicle and get away. You don’t have enough time to get to your concealed firearm. Use the car (or cars) as blocking device until you can draw your weapon or head for the hills – if possible.
When it comes to facing a lethal threat, distance is your friend. Distance + intervening solid object is even better. Cars and trees are ideal. But anything that keeps a bad guy or guys from being able to make physical contact is a very good thing indeed.
