To torture or not to torture?

Torturing 'does not get truth'

The extreme stress of torture harms the memory
Torture techniques used on suspected terrorists by the Bush administration may have failed to get to the truth, researchers say.

Professor Shane O'Mara of Trinity College, Dublin, said the interrogation techniques had a detrimental effect on brain functions related to memory.

He listed 10 methods of what he called torture used by the US, including stress positions and waterboarding.

His review is published in the journal, Trends in Cognitive Science.

'Lack of control'

Professor O'Mara said US Department of Justice memos released in April showed that the Americans believed that prolonged periods of shock, anxiety, disorientation and lack of control were more effective than standard interrogation in extracting the truth.

He said: "This is based on the assumption that subjects will be motivated to reveal truthful information to end interrogation, and that extreme stress, shock and anxiety do not impact on memory.


Techniques used by US
Walling - captive is placed with heels touching the wall and is pulled away and pushed back into it with force
Wall standing - captive stands four to five feet from wall with fingertips supporting all the body weight to induce muscle fatigue
Cramped confinement - captive place in small box in darkness for up to two hours, in a larger box for up to 18 hours
Sleep deprivation - captive is deprived of sleep for up to 11 days
Stress positions - captive sits on floor with legs straight out in front and arms raised above head or is made to kneel on the floor while leaning back at a 45 degree angle
Waterboarding - captive is bound head down on an inclined bench with a cloth over the eyes. Water is applied to the cloth for 20 to 40 seconds at a time inducing fast breathing and perception of drowning
"However this model of the impact of extreme stress on memory and the brain is utterly unsupported by scientific evidence."

He said studies of extreme stress with special forces soldiers had found that their recall of previously learned information was impaired afterwards.

"Waterboarding in particular is an extreme stressor and has the potential to elicit widespread stress-induced changes in the brain."

Professor O'Mara said contemporary neuroscientific models of human memory showed that the hippocampus and prefrontal cortices of the brain were very important.

The stress hormone, cortisol, binds to receptors in the hippocampus and prefrontal cortex increasing neuronal excitability which compromises the normal functioning of the brain if it is sustained.

And other stress hormones called catecholamines could lead to an increase in blood pressure and heart rate which could cause long-term damage to the brain and body if they were maintained at a high level for a long time.

Conditioning

Professor O'Mara said a common argument in favour of torture was that it would reliably elicit truthful information from the captive's long-term memory.

But psychological studies had suggested that during extreme stress and anxiety, the captive would be conditioned to associate speaking with periods of safety.

And because torture was stressful for the torturers the fact that the captive was speaking also provided a safety signal to the captor.

"Making the captive talk may become the end - not the truth of what the captive is revealing.

"These techniques cause severe, repeated and prolonged stress, which compromises brain tissue supporting memory and executive function.

"The fact that the detrimental effects of these techniques on the brain are not visible to the naked eye makes them no less real."

Memory disruption

Dr David Harper, a clinical psychologist from the University of East London, said the study appeared to be consistent with previous research on memory and trauma and with evidence of previous torture survivors and those in the intelligence community critical of psychological torture techniques.

"Believers in coercive interrogation tend to believe that people will 'tell the truth' as a result but much evidence suggests that people will, in fact, tell those conducting the torture what they think will make the torture stop.

"This has been noted as a danger by commentators from the Spanish Inquisition, through the Moscow Show Trials of the 1930s to the present day."

Dr Stuart Turner of the Centre for the Study of Emotion and Law said: "There is now very strong evidence that torture and harsh interrogation techniques may disrupt normal memory processes.

"With this in mind, it is also unreasonable to expect torture survivors to be able to give consistent and complete accounts of their experiences.

"This is highly relevant, for example, to the process of decision making for asylum seekers, arriving in the UK seeking refuge and for whom credibility is often a central issue.

"It appears that O'Mara's review paper supports the contention that to expect consistent memories in asylum applicants is unreasonable and therefore that inconsistencies should certainly not automatically be interpreted as evidence of fabrication."

Smoking ban heart gains 'massive'

Passive smoke raises heart risk
Bans on smoking in public places have had a bigger impact on preventing heart attacks than ever expected, data shows.

Smoking bans cut the number of heart attacks in Europe and North America by up to a third, two studies report.

This "heart gain" is far greater than both originally anticipated and the 10% figure recently quoted by England's Department of Health.

The studies appear in two leading journals - Circulation and the Journal of the American College of Cardiology.

Heart attacks in the UK alone affect an estimated 275,000 people and kill 146,000 each year.

Big impact

Earlier this month it was announced that heart attack rates fell by about 10% in England in the year after the ban on smoking in public places was introduced in July 2007 - which is more than originally anticipated.

But the latest work, based on the results of numerous different studies collectively involving millions of people, indicated that smoking bans have reduced heart attack rates by as much as 26% per year.

If you are a smoker, the single biggest thing you can do to avoid a heart attack is to give up, which could also protect the heart health of friends and family

Ellen Mason of the British Heart Foundation
Second-hand smoke is thought to increase the chances of a heart attack by making the blood more prone to clotting, reducing levels of beneficial "good" cholesterol, and raising the risk of dangerous heart rhythms.

Dr James Lightwood, of the University of California at San Francisco, led the Circulation study that pooled together 13 separate analyses.

His team found that heart attack rates across Europe and North America started to drop immediately following implementation of anti-smoking laws, reaching 17% after one year, then continuing to decline over time, with a 36% drop three years after enacting the restrictions.

Dr Lightwood said: "While we obviously won't bring heart attack rates to zero, these findings give us evidence that in the short-to-medium-term, smoking bans will prevent a lot of heart attacks.

"This study adds to the already strong evidence that second-hand smoke causes heart attacks, and that passing 100% smoke-free laws in all workplaces and public places is something we can do to protect the public."

Ellen Mason, of the British Heart Foundation, said: "These studies add to the growing evidence that a ban on smoking in public places seems to have a positive impact on heart attack rates, which is clearly good news for our nation's heart health.

"The statistics also show how quickly the benefits can be felt after a smoking ban is implemented and indicate how dangerous second-hand smoke can be to the heart.

"If you are a smoker, the single biggest thing you can do to avoid a heart attack is to give up, which could also protect the heart health of friends and family."

Latest figures show at least 70,000 lives have been saved by NHS Stop Smoking Services in the 10 years since they were established in England.

WASHINGTON -- An undercover video shot by an animal rights group at an Iowa egg hatchery shows workers discarding unwanted chicks by sending them alive into a grinder, and other chicks falling through a sorting machine to die on the factory floor.


Chicago-based Mercy for Animals said it shot the video at Hy-Line North America's hatchery in Spencer, Iowa, over a two-week period in May and June. The video was obtained Monday by The Associated Press.


Hy-Line said in a statement it has started an investigation "of the entire situation," adding that it would have helped their investigation "had we been aware of the potential violation immediately after it occurred."


The video, shot with a hidden camera and microphone by a Mercy for Animals employee who got a job at the plant, shows a Hy-Line worker sorting through a conveyor belt of chirping chicks, flipping some of them into a chute like a poker dealer flips cards.


These chicks, which a narrator says are males, are then shown being dropped alive into a grinding machine.


In other parts of the video, a chick is shown dying on the factory floor amid a heap of egg shells after falling through a sorting machine. Another chick, also still alive, is seen lying on the floor after getting scalded by a wash cycle, according to the video narrator.


Hy-Line said the video "appears to show an inappropriate action and violation of our animal welfare policies," referring to chicks on the factory floor.


But the company also noted that "instantaneous euthanasia" _ a reference to killing of male chicks by the grinder _ is a standard practice supported by the animal veterinary and scientific community.


According to Mercy for Animals, male chicks are of no use to the industry because they can't lay eggs and don't grow large or quickly enough to be raised profitably for meat. That results in the killing of 200 million male chicks a year.


The United Egg Producers, a trade group for U.S. egg farmers, confirmed that figure and the practice behind it.


"There is, unfortunately, no way to breed eggs that only produce female hens," said the group's spokesman, Mitch Head. "If someone has a need for 200 million male chicks, we're happy to provide them to anyone who wants them. But we can find no market, no need."


Using a grinder, Head said, "is the most instantaneous way to euthanize chicks."


Hy-Line says on its Web site that its Iowa facility produces 33.4 million chicks. Based on that figure, Mercy for Animals estimates a similar number of male chicks are killed at the facility each year. Hy-Line did not comment on that estimate.


Mercy for Animals says it will call on the nation's 50 largest grocery chains to include labels on their eggs that say, "Warning: Male chicks are ground-up alive by the egg industry."


Head called that proposal "almost a joke," saying the group had no credible authority, and had questionable motives. "This is a group which espouses no egg consumption by anyone _ so that is clearly their motive." The video does in fact end with a call for people to adopt a vegan diet, which eliminates all animal products _ meat, eggs or dairy.


Nathan Runkle, executive director of Mercy for Animals, said most people would be shocked to learn that 200 million chicks are killed a year.


"Is this justifiable just for cheap eggs?" he said.


As to more humane alternatives to disposing of male chicks, Runkle said the whole system is inherently flawed.


"The entire industrial hatchery system subjects these birds to stress, fear and pain from the first day," he said.
