Just throw in an onion
I was in a store the other day and was thinking about a situation. I was in the can vegetable isle, on the other side of the same shelf unit was can fruit. Would that be good cover from a bullet penetration? I figure it was 4’ – 6’ of cans stacked in front of me. I know it was good concealment but will it stop a bullet? If not how many cans would it take and can you use prep cans as defensive positions?
