Is AUTHOR wrong in the post ? POST : I am a teaching assistant (TA) at a division I public university. I am one of several TAs in a group where each of us lead a lab of ~30 students in a course. In November, as one of the TAs led a lab section, a student hesitantly approached him to let him know that when she used the bathroom, she saw a bomb threat scrawled on the wall. They were about halfway through class. 
The TA chose to continue class and asked the student to please let the front desk of the building know about the bomb threat. Within minutes, police and a bomb squad swarmed the building. The threat said the bomb would explode on Veteran’s Day which was a few days away. The TA told the story to the head TA and I, the senior TA, as one big joke. He said he was annoyed with the problem when it was brought to his attention, and did not want to deal with it. 
The entire school received an email detailing the threat, which was deemed not credible after Veteran’s Day. 
I think the TA did not handle this situation pragmatically. There were no consequences, punishments, or anything along those lines for that TA but we are now developing a protocol for how our TAs should handle potential emergencies so this doesn’t happen again. 

TL;DR a co-worker who is a teaching assistant was made aware of a bomb threat in the building he was teaching in and told the student who read the threat (written on a bathroom wall) to handle it and continued class. The bomb threat was eventually deemed not credible. I think he handled that irresponsibly.
