OCTOBER 30--A New Mexico cop shot a 10-year-old student in the chest with a 50,000-volt taser gun during a “career day” visit to the boy’s school, an accident that resulted in the officer’s brief suspension and recently triggered a civil lawsuit, records show. The child was hit with the taser probes during a demonstration earlier this year at Tularosa Elementary School, where Officer Christopher Webb spoke to groups of students in the school playground about gun and taser safety. While Webb claimed the taser “accidentally discharged,” the victim’s lawyers charge that the cop was recklessly joking around with students when the boy was struck with two electrified barbs.
