Expert says stun gun can kill hours later; firm calls claim 'ludicrous'

A growing number of deaths involving Tasers is fueling a debate among law enforcement officers, legislators, and state and federal regulators, who are asking if the electric stun gun is as safe as they were led to believe.
Now, a forensic engineer who has written safety standards for the most respected electrical laboratories and commissions in the world is warning police departments that shocks from Tasers could cause a delayed cardiac arrest and that injuries to officers and suspects who are zapped could be going undetected.
"Police should be informed that the Taser can kill," James Ruggieri told the American Academy of Forensic Examiners last week at its annual meeting. "The Taser can serve a useful role in law enforcement. However, it should not be touted as a harmless device."
Taser officials call Ruggieri's warning "ludicrous" and say their safety record is bolstered by the number of departments, including every major police agency in the Valley, that still use the stun gun.
Law enforcement agencies in California, Georgia, Ohio, Illinois, Indiana, Florida and North Carolina have backed off Taser deployments, citing safety concerns. Agencies also have expressed concern about officers shocking children as young as 6 and senior citizens as old as 82 over incidents such as refusing to pay for a salad at a Chuck E. Cheese restaurant.
"Those administrations who have transitioned to Tasers feel more caught in the middle," said Fort Wayne, Ind., Police Chief Rusty York, who vetoed the planned purchase of 83 stun guns last month.
"I am a little skeptical about the assertion that no one has been killed or injured by Tasers," he said. "But (other) police departments were taking the advice from Taser and running with it. I agree that the stun gun is a useful tool, but until we can have more objective information about Tasers . . . I'm not going (forward)."
Conflicting studies
Ruggieri, who has served as a forensic investigator for the Fairfax County Police Department in Virginia and has consulted with the Occupational Safety and Health Administration, the Federal Aviation Administration and the National Transportation Safety Board on electrical accidents, said his research cuts to the heart of Taser's safety claims and represents one of the first scientific and medical reviews that is critical of the stun gun.
His recommendation: Police should stop shocking officers during training exercises and use the stun gun on suspects only when no other non-lethal option is available.
Rick Smith, chief executive officer of Scottsdale-based Taser International, maintains that Tasers have never caused a death or serious injury, and he cites more than 90 studies by universities, the military and police departments that support Taser's safety claim. He challenged Ruggieri's presentation to the forensic academy and questioned his ability to cite medical findings because Ruggieri is not a doctor.
"His misapplication of the safety standards, coupled with the misstatement of Taser incidents . . . make us question his motivation," Smith said. "He has never touched a Taser, never seen a Taser, never used a Taser. . . . How can he make scientific judgments on the technology?"
Ruggieri said that his findings come from research of medical data and that he has never claimed to be a doctor. He said he has extensive knowledge of stun guns and has handled dozens of them, including Taser's signature weapon, the M26. He owns two stun guns, made by different manufacturers.
A Taser looks and operates like a plastic gun. It fires two steel barbs up to 21 feet and delivers a 50,000-volt burst of electricity that causes involuntary muscle contractions. It works by momentarily incapacitating suspects, who usually recover once the power is cut. Taser officials say the gun cannot cause heart attacks.
More than 7,000 of the nation's 18,000 law enforcement agencies have armed officers with Tasers. Police credit Tasers with reducing injuries to officers and suspects, lowering the number of police shootings and shrinking the number of liability claims. They say the stun gun is an invaluable tool.
Taser stock prices dropped this year after revelations that the U.S. Securities and Exchange Commission and the Arizona attorney general had launched inquiries into the company's claims of safety and into an end-of-year sale that helped the company meet annual projections.
An ongoing investigation by The Arizona Republic has found that 101 people have died in the United States and Canada following police Taser strikes since 1999. Medical examiners have cited the Taser in 12 of those deaths, calling it a cause of death in three cases and a contributing factor in six others. In three other cases, examiners said they were unable to rule it out as a cause of death.
Deaths and safety concerns have prompted the International Association of Chiefs of Police to call for every police department to conduct a review of its Taser policies. And a California legislator last week introduced a bill that would require every department in the state to track each time an officer drew a Taser, so the data could be analyzed by the U.S. Department of Justice.
Wisconsin's attorney general said concerns about the way police use stun guns led her to call for a statewide standard. However, the Madison Police Department has praised the stun gun.
"The Taser is extraordinarily effective in controlling resistive subjects, while also being extraordinarily safe," the department reported last month. "There is no question that both the number and severity of injuries (to both officers and suspects) would have been far higher but for the Taser."
Other law enforcement agencies aren't so sure.
"The policy right now is that Tasers are not to be used in this building," said Rick Keller, administrator of the Lucas County Corrections Center in Toledo, Ohio, where an inmate died Jan. 31, moments after being shocked multiple times by deputies.
Not only have Tasers been suspended inside the jail, but any suspect who has been shocked by police before being booked will now be taken directly to the hospital for a medical examination.
"I don't think there is a good answer," Keller said. "If you have someone die, and it comes back that Tasers contributed to (the death), that is not good. But you have to do something to restrain him."
Keller said officers are concerned about the stun gun being taken away. But he said the Sheriff's Office, which runs the jail, wants to determine if Tasers are safe before allowing them back into circulation.
Taser expansion was halted in Chicago after police, in two separate incidents last month, shocked a 54-year-old man who later died and a 14-year-old boy who went into cardiac arrest.
"We have taken a very deliberate approach to these weapons," said Dave Bayless, a Chicago police spokesman. "We have had one death, and that has prompted us to slow down deployment."
Although the department did not recall existing Tasers, Bayless said, officials want to study the safety of the stun gun before deploying it in multiple police districts. Chicago police acknowledge concerns about the stun gun, but officials also say there are plenty of success stories.
"It is a good debate to have," Bayless said. "It holds police accountable. It also gives us an opportunity to explain to the public the very real dangers that police face every day."
David Murphy, criminal-justice assistant professor at Weber State University in Utah, has been contacted by several agencies about conducting a safety study of the weapon.
Some Utah police agencies have bought Tasers but not put them on the street for fear that the stun guns might not be as safe as the manufacturer claims.
Looking for a trend
The foundation of Taser safety is based on the assertion that shocks from Tasers cannot induce heart attacks. Taser officials insist that if Tasers were able to cause a heart attack, it would occur immediately upon being shocked.
Ruggieri said evidence shows that heart damage and fatal heart rhythms can develop hours after electrical shock occurs. He said suspects and police officers, who are routinely subjected to Taser shocks during training, "may have unknowingly incurred permanent heart damage."
Smith said that if Ruggieri was right, there would be hundreds, if not thousands, of cases in which Tasers would have caused either heart attacks or injured internal organs.
"Out of 200,000 (people) who have been shocked, we would have seen credible evidence of that," he said.
For years, Taser has encouraged officers to experience shocks during training. The company claims that more than 100,000 officers have been shocked during training without incident.
Last year, however, The Republic found that several officers have suffered career-ending injuries that they attribute to Taser shocks, including cardiac problems.
In one case, a doctor hired by Taser concluded that a one-second burst from a Taser was responsible for fracturing the back of a former Maricopa County sheriff's deputy. The deputy, Sam Powers, has filed the first private liability lawsuit against Taser. His case is expected to go to court in June.
Taser has blamed Powers' injuries on pre-existing conditions, including osteoporosis.
Phoenix lawyer John Dillingham, who represents Powers, said Ruggieri's presentation should be an alarm bell for police.
"We totally agree that law enforcement should never willingly be subjected to a shock," he said.
Medical examiners, who are at the forefront of the Taser debate and make rulings in cases of deaths following Taser strikes, said Ruggieri's presentation will induce further debate and more research.
"There hasn't been any real medical evidence on either side," said Lake County, Ind., Forensic Pathologist John Cavanough, who added that Ruggieri raised relevant issues, particularly in regards to the delayed cardiac arrest.
"It is a real phenomenon," Cavanough said. "As a matter of fact, that (the warning about delayed cardiac arrest) was his strongest point."
Ruggieri, whose presentation will go through a peer-review process before being published in the Journal of Forensic Science, said his findings could lead medical examiners to re-examine past cases of death following a Taser shock.
Thomas Parsons, a medical examiner from Daytona Beach, Fla., said that he believes Tasers are an important tool for police and that many deaths were likely not the fault of Taser.
"Tasers are an excellent less-than-lethal option for police who are properly trained to use them," he said, adding that many of the deaths following Taser shocks would have occurred with or without the stun gun.
"(Ruggieri's) research ideas were controversial, but his recommendations were reasonable," Parsons added.
Taser officials say they remain steadfast behind Taser technology. Smith said Tasers have strong support from law enforcement and the public.
"We have been taking a beating in the press," he said. "But at its core, our product is as safe as ever."
