A Jefferson County teacher picked the wrong example when he used assassinating President Barack Obama as a way to teach angles to his geometry students.
Someone alerted authorities and the Corner High School math teacher was questioned by the Secret Service, but was not taken into custody or charged with any crime.
"We did not find a credible threat," said Roy Sexton, special agent in charge of Birmingham's Secret Service office. "As far as the Secret Service is concerned, we looked into it, we talked to the gentleman and we have closed our investigation."
Teachers should know better.
