According to a letter sent out to the campus from CSU Police Chief D. Yarbrough, a man was spotted at 8:30 a.m. with a large rifle on the west side of the Clark Building. CSUPD responded, brandishing shotguns, in less than one minute and searched the building. Several of the responding officers were still wearing civilian clothes due to the urgency of the call, according to Yarbrough. The letter says campus police determined the man with the rifle was actually a history professor who had brought the firearm in for demonstration purposes for a Civil War class. The professor was given instructions on how to properly bring a rifle to campus for demonstration purposes, according to campus police. Yarbrough says the Clark Building was never evacuated and students, faculty and staff were never in any danger. Gotta love it, no matter how many degrees you have you may never find that common sense you have been searching for.
