I have never thought about this at an Australian university. I cannot imagine the extra stress of school and university educators to think about keeping their students safe from mass shootings. My husband is American. I will never live there until there is gun control. Stay safe US colleagues.
Each semester I go in my classroom and I try to figure out what we would use to block the doors, if it would be safe to crawl out the windows, where we could hide if there was a mass shooter in campus. It’s such an indictment of this country how we have normalized these preventable tragedies.
