Sacha van Loo, 36, is not your typical cop. He wields a white cane instead of a gun. And from the purr of an engine on a wiretap, he can discern whether a suspect is driving a Peugeot, a Honda or a Mercedes.
Van Loo is one of Europe's newest weapons in the global fight against terrorism and organized crime: a blind Sherlock Holmes, whose disability allows him to spot clues sighted detectives don't see.
"Being blind has forced me to develop my other senses, and my power as a detective rests in my ears," he said from his office at the Belgian Federal Police, where a bullet-riddled piece of paper from a recent target-shooting session was proudly displayed on the wall. "Being blind also requires recognizing your limitations," he added with a smile, noting that a sighted trainer guided his hands during target practice "to make sure no one got wounded."
