Teacher uses Obama assassination as math example

BIRMINGHAM, Ala. (AP) — A Jefferson County geometry teacher was placed on paid administrative leave this week after being accused of using a hypothetical assassination plot on President Barack Obama as a way to teach geometric angles.

School Superintendent Phil Hammonds said Corner High School teacher Gregory Harrison could face possible termination.

Hammonds earlier said the teacher remained at work and there were no plans to fire him. But in announcing that the teacher was being placed on leave, the superintendent said his office had been flooded with calls from people around the nation, mainly upset that further action hadn't been taken against the teacher.

Roy Sexton, special agent in charge of Birmingham's Secret Service office, said his agency spoke with the teacher after being told about his comment, but no charges were filed and the investigation was closed.

"We did not find a credible threat," Sexton said.
