Stun gun orders are pouring in

PHOENIX (AP) -- From Korean Air flight crews to U.S. police and corrections officers to beat cops in Britain, the orders are pouring in for stun guns made by Taser International Inc.
The Scottsdale company even recently launched a metro Phoenix ad campaign urging private citizens to arm themselves with the weapons, which temporarily paralyze people with a 50,000-volt jolt.
Yet while Taser's stock has soared with the booming business, concerns are growing about whether the shock-inducing guns are truly as nonlethal as advertised.
In a report being released today, Amnesty International says stun guns are being abused by police and wants more scientific study done to determine whether the devices are safe.
Amnesty says at least 74 people have died in the United States and Canada in the past four years after being shocked with Tasers.
The group also says officers have turned stun guns on the mentally disturbed, children and the elderly.
"Not only do we not know the impact of these weapons on human beings under various conditions, we are also concerned about the gratuitous use of these weapons," said Gerald Le Melle, deputy executive director of Amnesty International USA.
A Defense Department-sponsored report also calls for more testing, and some health professionals are expressing concern that the potential for cardiac arrest could be too high.
