Europe has new counterterrorism weapon: Blind detectives 

By Dan Bilefsky

ANTWERP, Belgium: 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."

Van Loo, a slight man who has been blind since birth, is one of six blind 
police officers in a pioneering unit specializing in transcribing and analyzing 
wiretap recordings in criminal investigations. An accomplished linguist who 
taught himself Serb Croat for fun, he laments that he is not entitled to carry 
a gun on the job or make arrests. But such is his acute sense of hearing that 
Paul van Thielen, a director at the Belgian Federal Police, compares his powers 
of observation to those of a "superhero."

When police eavesdrop on a suspected terrorist making a phone call, van Loo can 
listen to the tones dialed and immediately identify the number. By hearing the 
sound of a voice echoing off of a wall, he can deduce whether a suspect is 
speaking from an airport lounge or a crowded restaurant. After the Belgian 
police recently spent hours struggling to identify a drug smuggler on a faint 
wiretap recording, they concluded he was Moroccan. Van Loo, who has a "library 
of accents in his head," listened and deduced he was Albanian, a fact confirmed 
after his arrest.

"I have had to train my ear to know where I am. It is a matter of survival to 
cross the street or get on a train," he said. "Some people can get lost in 
background noise, but as a blind man I divide hearing into different channels. 
It is these details that can be the difference between solving and not solving 
a crime."

Grappling with his handicap, he says, also has given him the thick emotional 
skin necessary for dealing with the job's stresses. "I have overheard criminals 
plotting to commit murder, drug dealers making plans to drop off drugs, men 
beating each other up. Being blind helps not to let it get to me because I have 
to be tough."

The blind police unit, which became operational in June, originated after van 
Thielen heard about a blind police officer in the Netherlands, and was looking 
at ways to improve community outreach. He made the connection that blind people 
could prove more adept than the sighted at listening to and interpreting 
wiretaps. That idea, he says, was given added impetus after the Belgian 
government passed a law a few years ago giving the police extended powers to 
use wiretaps in the investigation of 37 areas of crime, including terrorism, 
murder, organized crime and the abduction of minors.

The police also recognized that blind officers like van Loo could be 
particularly valuable in counterterrorism investigations because wiretap 
recordings - derived from a phone tap or bug placed in the safe house of a 
terrorist group - are often muffled by loud background noise, requiring a 
highly trained ear to discern voices. Alain Grignard, a senior counterterrorism 
officer at the Brussels Federal Police, notes that wiretaps proved instrumental 
in the recent arrests of a large terrorist cell in Belgium recruiting for the 
insurgency in Iraq.

Beyond his keenly developed ears, van Loo is also a trained translator who 
speaks seven languages, including Russian and Arabic - a skill Grignard said 
makes him indispensable, since his knowledge of accents can help him to 
differentiate between, say, an Egyptian or Moroccan suspect. "You need every 
edge in a terrorism investigation, and a blind officer with languages could be 
a powerful weapon."

The Belgian police say they were amazed at the number of qualified blind 
applicants for the posts. Scoring high marks on a hearing test was a 
prerequisite for the job, as was being at least 33 percent blind. Van Thielen, 
the police chief, says he was forced to turn away dozens of applicants whose 
sight was too good, including one "blind" man who shocked police recruiters by 
arriving at his interview in a car.

Recruiting blind people posed other challenges, van Thielen recalls. Because 
they would be used almost exclusively for wiretap investigations and the force 
did not want to expose them to dangerous situations, they were given special 
status under a 2006 law tailored for forensic work that grants civilians some 
police powers, but forbids them from making arrests or carrying guns.

Van Thielen, a no-nonsense police veteran, also faced some resistance from 
other veterans on the force, who feared that having blind colleagues would be a 
burden. Others felt awkward about how to behave in front of blind people and 
wondered if saying "au revoir" - literally "see you again" - would cause 
offense. To assuage their concerns, van Thielen arranged for sensitivity 
training sessions with blind volunteers. One hint: don't leave computer cables 
trailing on the floor since blind officers could trip on them.

"At first when members of the police heard that blind people were coming to 
work here, they laughed and told me that we were a police force and not a 
charity," said van Thielen. "But attitudes changed when the blind officers 
arrived and showed their determination to work hard and be useful."

It wasn't only attitudes that needed updating. In addition to installing 
elevators with voice-activated buttons at the police station, the force issued 
each blind officers with a special ?10,000 computer equipped with Braille 
keyboards, and a voice system that transmits visual images into sound.

As van Loo transcribed a wiretap recording on a recent day, he wore earphones 
and passed his index finger over a long strip of Braille characters on the 
bottom of the keyboard, whose characters altered to replicate whatever was on 
his computer screen, which was turned off. When he goes outside, he carries a 
compact police-issued global positioning system device, with a voice that 
directs him to his destination, street by street.

A father of two, van Loo attributes his success to having parents who taught 
him at an early age to be independent. He recalls that, as a young child, his 
father, a film buff, took him to watch movies. His father also taught him to 
drive a car by hoisting him on his lap and guiding his hands on the steering 
wheel. His ability to adapt, he says, was further reinforced by his attending a 
regular high school. He also attended a special school for the blind, where he 
learned how to maneuver with a cane and to read Russian in Braille. To relax, 
he skis, rides horses and plays the Arabic lute.

"My parents accepted my blindness, which also helped me to accept it," he said. 
"That they were not risk averse also helped."

Cindy Gribomont, head of training at the Brussels-based Braille League, an 
institute for the blind that helped the police with recruiting, says that 
overcoming employers' prejudices is her greatest challenge. "Employers need to 
be encouraged because they are afraid of employing handicapped people."

Van Loo, for his part, says he remains determined not to let his handicap 
overwhelm him. "Being blind isn't always very easy," he said. "I don't focus on 
it. I don't deny it. But it is rather tragic that a blind policeman is still 
viewed as an exception."
