And back in the United States, Amnesty International is calling for new limits on the use of taser stun guns by law enforcement officials. In a new report, Amnesty says 334 people have been killed by taser weapons since 2001. 90 percent of the victims were unarmed and did not appear to present a serious threat. Some of the people to be shocked by taser weapons include schoolchildren, pregnant women and an elderly person with dementia.
