Teacher Makes Chalkboard Gun Threat Warns period 6: 'Care to try me?' By Matt Cantor, Newser User Posted Mar 5, 2013 1:59 PM CST 28 comments Comments A screen grab from CBS video of the chalkboard. (CBSChicago) (Newser) – An Indiana high school business teacher has admitted to writing a threatening message on a chalkboard. "Period 6 (only)," it reads: "(A) You are idiots!!!! (B) The guns are loaded!!! (C) Care to try me????" The teacher "had been absent two days prior, and he was reacting to some comments that were made by the substitute teacher," an official says. The longtime teacher was sent off campus; whether he'll keep his job is unclear, CBS 2 reports. A student took a picture of the message, which a school official spotted while monitoring student Facebook pages. "We’re not saying in fact that there is a threat. That’s what we’re determining by interviewing the students, the staff," says a police chief.
