In this day and age, prison complexes feature state-of-the-art detection systems that make it hard for inmates to escape undetected. Nevertheless, it’s always a good idea to have a backup system in case the sophisticated stuff fails to work. Human guards and guard dogs are the norm, but some prisons have taken to using unlikely alternatives. For example, a prison in Santa Cantarina, Brazil, recently replaced its guard dogs with a flock of geese that make loud noises when they detect the sounds of someone trying to escape. The “geese guards” patrol the space between the prison’s inner fence and its main outer wall. Since introducing the hissing flock of honking geese, there hasn’t been one escape attempt. You have to wonder if when patrolling the geese are “goose stepping.”
