Should teachers be able to carry guns at school?

Joe Scarborough's show on MSNBC will discuss the issue of whether teachers should be able to carry guns at school tonight at 10PM ET. I will be discussing the issue with a criminal psychologist and an official of one of the teachers' unions for about 8 minutes.
