Texas has adopted a law that allows students to bring a handgun to class, or to meetings with professors.
As a response to this policy, the president of the Faculty Senate, Jonathan Snow, gathered a group of faculty and gave a powerpoint presentation that included the slide at the top of the post.
Snow’s presentation was not any sort of official university statement, but the slide does a good job of demonstrating the likely effect on faculty student relationships under the conditions where students are more likely to pull out a handgun and plug the professor.
The situation, and the context for this presentation, are written up in this post at the Chronicle of Higher Education. PZ Myers discusses it here. The powerpoint presentation is available here.
A suitable response faculty may consider is here.
