Working as a police officer had taught him firsthand that locks don’t work. They slow criminals down, sure—but they don’t really stop anyone. Maybe your lock means that a burglar will need a few more minutes to get inside—but they’ll still get inside. If you really want to keep people out of a space altogether—if you want to end the humiliation of burglary—then you need something far stronger than a dead bolt. You need an absolute physical barrier.
