London, May 19 (ANI): Using examples didn't really suit a teacher in Alabama, who found himself at the centre of a US Secret Service investigation for using a hypothetical assassination of President Barack Obama as a way to teach geometric angles.
However, the police found that Obama was not under threat.
Officials said the Corner High School teacher apparently was instructing his students about parallel lines and angles and used the example of where to stand and aim to shoot the president.
However, the incident alerted the authorities, and Roy Sexton, special agent in charge of Birmingham's Secret Service office, said his agency spoke with the teacher.
"We did not find a credible threat," the Telegraph quoted Sexton as saying.
And no charges were filed against the teacher.
Jefferson County school officials said that Supt Phil Hammonds declined to release the teacher's name.
The teacher remains at work and there are no plans to fire him, according to police.
"We are going to have a long conversation with him about what's appropriate. It was extremely poor judgment on his part, and a poor choice of words," Supt Hammonds told The Birmingham News.
Joseph Brown, a senior in the geometry class, told the News that teacher "was talking about angles and said, 'If you're in this building, you would need to take this angle to shoot the president.'" (ANI)
