The only account I have read so far is the one from the young man who lived through the French class assault. According to him, everyone was laying down on their bellies once the bullets started coming through the door. No one got up to run or fight back. Perhaps teaching and training could be done for a class caught in this situation. Throwing books, chairs or anything not fastened down might make the intruder protect themselves long enough for some to rush them. This will happen again, we just don't know when, where and to what extent.
Does VT have an ROTC unit?
