Fifteen minutes later the officer came into our classroom and told us what had happened when he approached the man. It was not what anyone expected. When questioned about why he was loitering outside the classroom, the elderly man responded, "I'm just waiting for my mom to pick me up. She should be here any second."
Obviously, the officer's whole approach to the man changed after hearing those words. It was clear that the man was suffering from the early stages of Alzheimer's or dementia. The officer kindly redirected the man to another area of the prison where he could "wait for his mom to pick him up" without being disturbed by others, and without calling unwanted security attention to himself.
When I heard that story my heart broke. That man should be in a mental hospital.
