I think it goes beyond that, Mariann. Students with psychological disabilities -- or those who are BELIEVED to have psychological disabilities -- are likely to face significant discrimination in our society today, and the higher education setting is no exception. In general, we are afraid of people we perceive as "different" or whose behavior is outside the norm. After incidents like Virginia Tech, such students are often shunned and isolated further by faculty and students alike out of our own fears. I think it is important to keep in mind that the number of students who are dangerous (to themselves or to others) is minimal, and not to OVER respond to the behaviors we observe in such students.
