UN - Using taser guns is torture 

The United Nations has linked taser stun guns to torture, just a month before police here release a report on the weapons.
 
The UN Committee against torture says tasers cause acute pain, constituting a form of torture.
 
Its declaration comes after a second death in Canada, linked to a taser.
 
A man has died in British Columbia, four days after police used a stun gun on him, saying he was acting erratically in a shop.
 
Earlier this month, a Polish immigrant died after Canadian police tasered him at Vancouver Airport.
 
A year-long test of tasers ended here in August and a decision on their long-term use is due early next year.
