One of the latest in our national epidemic of school shootings happened at Purdue University in West Lafayette, Indiana. Some startling video has surfaced of an economics class in session while the building is evacuated.

The video was uploaded by the professor who was conducting the lecture and includes this YouTube description:

video i posted on facebook of the recording of my lecture when we were evacuated I edited to the first moment we heard shouting. Large lecture room in the Electrical Engineering building where the shooting took place. The cops are heard yelling outside the room before anyone knew what was going on. Then we were evacuated
