Is this a real-life 'light saber?'

By Mimi Hall and Eric Moreno, USA TODAY
The Homeland Security Department is aiming to arm federal agents with
a light-saber-type weapon that emits a dazzling strobe capable of
subduing criminals, terrorists and even unruly airline passengers.
It's the latest government effort to develop a non-lethal weapon - in
this case, a powerful beam of light that temporarily blinds anyone who
looks into it.

"The light could be used to make a bad guy turn away or shut his eyes,
giving authorities enough time to tackle the suspect and apply the
cuffs, all while sparing the lives of passersby, hostages or airline
passengers," according to a description of the device from the
Homeland Security Department's science and technology division.

Program manager Gerald Kirwin says Homeland Security has invested $1
million for testing of the LED (light-emitting diode) Incapacitator.
It is being developed by a Torrance, Calif., company, Intelligent
Optical Systems, and it will be tested on volunteers at Pennsylvania
State University's Institute of Non-Lethal Defense Technologies this
fall.

If all goes well, the Homeland Security Department says it "could be
in the hands of thousands of policemen, border agents and National
Guardsmen" by 2010. Kirwin says it also would be used by air marshals,
border patrol agents, other officers with the Transportation Security
Administration and customs officers.

The device works by temporarily blinding and disorienting a person,
says Bob Lieberman, president of Intelligent Optical. Once aimed at
someone's eyes, a series of light pulses and colors can be triggered
and the subject's eyes can't adjust quickly enough to see.

"It's like someone shooting off a flashbulb in your face every few
seconds," Lieberman says. "Because of the wavelengths and frequencies
we use, there are psychophysical effects - a real disorientation. The
reaction can range through vertigo to nausea."

That's why The Register, an irreverent online publication that covers
the information technology industry, dubbed it the "puke-ray."

What the flashlight-size device doesn't do, however, is use lasers or
permanently blind people, Lieberman says. In 1995, the United States
signed on to a United Nations agreement that banned blinding weapons.

"We're taking great care to make sure the intensities we're using fall
within eye-safe limit," Lieberman says. "We're doing medically
supervised tests."

But some immigration and human rights groups say they're still
concerned, particularly with the idea that the devices might be used
on illegal immigrants.

"It gives me pause, particularly in regards to Mexico. Mexico is a
very important economic partner of ours," says Deborah Notkin,
president of the American Immigration Lawyers Association.

"I would imagine that Mexico wouldn't be particularly happy with us
using a device that would be more appropriate for criminals, not just
for people trying to get across the border who are looking for better
opportunities."

Peter Herby, head of the mines-arms unit's legal division at the
International Committee of the Red Cross in Geneva, says he's not
familiar with Homeland Security's new weapon. But he says many of the
same issues are likely to crop up as with more dangerous, laser-based
blinding weapons - called "dazzlers" because they blind people with
intense light.

Among the issues: If the devices are mass-produced and fairly
inexpensive, they're likely to be sold on the black market.

"Once they're in the hands of bad guys," Herby asks, "are the police
going to have to wear protective gear to prevent them(selves) from
being dazzled?"
