When I was an undergrad at Texas A&M, it was not uncommon for jerks to call in bomb threats to get out of an exam. When I was a grad student at Georgia Tech, we received a memo on how to avoid being a victim of the Unabomber. When I taught at the University of Arkansas, a fellow professor (in a different department) was killed by a former graduate student. I know a couple of engineering faculty at Virginia Tech - no word yet on whether they are among the dead.
I had a "business breakfast" this morning with a visitor from Virginia Tech. What a horrific day VT had.
Do you ever get the feeling that no place is safe?
