[Marxism] Chicago Study Calls Taser's Safety Claims Into Question

[Greg McDonald <sabocat59@xxxxxxx>]

I'm posting this one for Fred Feldman, inveterate pig lover. I say we  
test the tasers out on the human porkers.  Much as advocates of  
waterboarding should enjoy the experience of fresh water clearing out  
their lungs, so too perhaps our local constabulary should benefit  
from frequent and prolonged shocks to their system. Perhaps THAT  
would waken their dormant ethical sensibilities.

Chicago Study Calls Taser’s Safety Claims Into Question

Taser stun guns may not be as safe as their manufacturer claims,  
according to a study carried out by Chicago researchers, CBC News has  
learned.

The team of doctors and scientists at the trauma centre in Chicago’s  
Cook County hospital stunned 11 pigs with Taser guns in 2006, hitting  
their chests with 40-second jolts of electricity, pausing for 10 to  
15 seconds, then hitting them for 40 more seconds.

When the jolts ended, every animal was left with heart rhythm  
problems, the researchers said. Two of the animals died from cardiac  
arrest, one three minutes after receiving a shock.

The findings call into question safety claims made by Taser  
International, the Arizona company that makes the stun guns, which  
are used by dozens of police departments across Canada.

According to Taser International’s website, “independent medical and  
scientific experts have determined Taser devices to be among the  
safest use-of-force options available.”

Taser director Mark Kroll has also published a paper called Safety of  
Taser Electronic Devices, in which he says when electricity kills, it  
is an immediate death that occurs within four seconds because  
electricity can’t linger in a living being’s body “like a poison.”

But Bob Walker, one of the lead researchers on the Chicago study,  
said the fact that one of the pigs died three minutes after being  
stunned is significant.

“It says that the effect of the Taser shot can last beyond the time  
when it’s being delivered,” he said. “So, after the Taser shock ends,  
there can still be effects that can be evoked and you can still see  
cardiac effects.”

Thomas Smith, the co-founder of Taser International, is set to  
testify before the parliamentary committee on public safety and  
national security in Ottawa on Wednesday, where he’ll face questions  
on the safety and use of the weapons.

Officers need to ask questions: researcher

Dr. Andrew Dennis, a trauma surgeon and ex-police officer who worked  
on the study, said if Tasers can affect pigs, more research needs to  
be done to study how safe the stun guns are. In the meantime, police  
should question when, and on whom, they use the devices, he said.

“The officers need to question themselves and ask themselves, ‘Is  
this the appropriate situation for this device?’ ” Dennis said. “They  
need to have the understanding that this is not a truly benign device.

“What I would not want to see is an individual police officer  
thinking that this device can [be] used with impunity, because I  
think there are certain risks to this device.”

Stun gun safety was called into question after Robert Dziekanski, a  
40-year-old Polish man, died at Vancouver International Airport after  
being shocked with a Taser by police on Oct. 14, 2007. Dziekanski’s  
death renewed calls for a moratorium on Taser use.

‘The human studies are clearly much more relevant’

Other Taser studies have been done on pigs and humans in the past -  
some finding medical problems with the stun guns, and others not -  
but the Chicago researchers said they wanted to do a study where  
subjects were exposed to longer bouts of the guns’ electrical currents.

Because the researchers opted for 40-second jolts, their ethics board  
wouldn’t allow them to use human subjects.

Rick Smith, the CEO of Taser International and company co-founder,  
doesn’t think much can be concluded from the Chicago study because it  
focused on pigs that weigh less than 100 pounds and have a very  
different physiology from humans.

Smith said studies done on humans have shown Tasers don’t pose a  
serious health threat.

“The human studies are clearly much more relevant to policy-makers,  
and to people that are interested in the science of how Tasers affect  
people,” he said.

Dr. Jeffrey Ho, a researcher who has studied stun guns in the past,  
but was not involved in the Chicago study, stressed that the guns may  
not have the same effect on people as they did on the pigs in Chicago.

“I think animals are good surrogates for research models in some  
situations,” said Ho, an associate professor of emergency medicine at  
the University of Minnesota. “In my modelling, I prefer to use humans.”

However, pig studies have been used as evidence in arguments for and  
against stun guns in the past. Even the Taser International website  
points to studies on pigs in which the outcomes suggest the stun guns  
aren’t a serious safety risk.
