Six blind men

"You need every edge in a terrorism investigation, and a blind officer with languages could be a powerful weapon."

Yes, you read that right. The Belgian police have taken on 6 blind men, because the blind have a more acute sense of sound and can thus be far more effective when listening to wiretaps. For instance Sacha van Loo can not just figure out whether the suspect the police is tracking is driving a Mercedes or a Honda, he can even tell you which number has been dialled, by just listening to number tones on a mobile phone. He's a linguist as well, which enables him to identify the nationality of kidnappers and terrorists just by listening to them speak.

Sort of reminds you of the Six blind men of Hindoostan, doesn't it?
