CBS/AP) A United Nations committee said Friday that use of Taser weapons can be a form of torture, in violation of the U.N. Convention Against Torture.
Use of the electronic stun devices by police has been marked with a sudden rise in deaths - including four men in the United States and two in Canada within the last week.
Canadian authorities are taking a second look at them, and in the United States, there is a wave of demands to BAN them.
The U.N. Committee Against Torture referred Friday to the use of TaserX26 weapons which Portuguese police has acquired. An expert had testified to the committee that use of the weapons had "proven risks of harm or death."
"The use of TaserX26 weapons, provoking extreme pain, constituted a form of torture, and that in certain cases it could also cause death, as shown by several reliable studies and by certain cases that had happened after practical use," the committee said in a statement.
"Well, it means that it's a very serious thing," Amnesty International USA Executive Director Larry Cox told CBS Early Show co-anchor Julie Chen. "These are people that have seen torture around the world, all kinds of torture. So they don't use the word lightly."
Tasers have become increasingly controversial in the United States, particularly after several notorious cases where their use by police to disable suspects was questioned as being excessive. Especially disturbing is the fact that six adults died after being tased by police in the span of a week.
Last Sunday, in Frederick, Md., a sheriff's deputy trying to break up a late-night brawl tased 20-year-old Jarrel Grey. He died on the spot.
"I want to know what he did that was so bad," the victim's mother, Tanya James, said. "Did the deputy think that their life was in danger? Did he have a weapon?"
The death came just weeks after Frederick police used a Taser to subdue a high school student.
Black leaders held a rally Tuesday calling for the department to ban Tasers, at least until there is a clear policy on how they are used. The NAACP says it appears the sheriff's office is using Tasers routinely, rather than as a weapon of last resort.
Also this week, in Jacksonville, Fla., in two separate cases two men died after being stunned.
One suspect, who fled a car crash and tried to break into a nearby home, struggled with a policeman, prompting the officer to tase him three times. The man continued to fight, and tried to bite the officer, while he was being tased. He was later pronounced dead at a hospital.
Another man died Tuesday after a Jacksonville officer pulled over his car. When the officer approached it, the man took off running. When the officer caught up with him, during a struggle, authorities say the officer used his Taser to subdue the suspect.
After being placed in the back of the police car the suspect became unresponsive. He was taken to the hospital where he was pronounced dead.
Last Sunday, in New Mexico, 20-year-old Jesse Saenz died after Raton police used a Taser to subdue him. Police say Saenz was struggling and fighting with them as they attempted to take him into custody.
Saenz died after being transported to a county jail.
