I would lean toward not giving him a release if I were the Va Tech AD. If the guy is in mortal fear and won't be able to sleep at night maybe I'd give it to him after a psyschiatric evaluation and recomendation. However, he is just saying he doesn't want to go because the campus will be in mourning. That is a lame, and I suspect untrue, reason. I wouldn't hold the AD at fault for not releasing.
