6. He was deaf but still committed robbery, so he didn't hear the alarm.
In August 1995, Klaus Schmidt stormed into a Berlin bank with a handgun and demanded cash. But strangely, when a bank employee asked if he needed a bag to hold the money, the robber replied, "Damn it, of course this is a real gun!"
This small detail helped witnesses realize the robber was deaf. Taking advantage of the situation, an employee pressed the alarm button. Despite the loud ringing, the robber calmly continued threatening the employees, completely unaware.
When police arrived, they quickly arrested Klaus Schmidt. However, Schmidt later filed a counterclaim against the bank for exploiting his disability.
