An emergency management director in northeast Tennessee is facing a state investigation for a mock drill that shocked the county commission last night. Ernest Jackson says he's taking the nation's war on terror seriously and was just trying to do his job. He says he had informed some participants of the drill, but did not specify how it would be carried out. The drill in Elizabethton had a man and a woman rushing in carrying guns. They held a weapon to the head of county finance director Jason Cody and said there would be no new taxes. One of the bogus hostage-takers fired a blank. County commissioner Jack Buckles says this drill could have "turned bad real quick." He says there were uninformed law enforcement officers in the audience who were in the process of reaching for their guns.
