learn from the criminals do box windows ” fake one” with scrap wood from pallet you can make your steel core door not break after 12 + hits from a door breaker LE style. but if you have glass next to it how long before that gets broken and a hand reaches for the lock? do you have other lock pins in place. do you have an clear line of sight of your front door? your backdoor? have a cage or materials for a second door right behind the first. using nothing more than heated sand and an air compressor you can make a confined space a nightmare
