I think in Australia too then, post-covid, students may have become a bit more unruly, and classroom routines and expectations need to be re-taught and reestablished. The unruliness generally doesn't generally rise to the level of safety concerns, although there was a case recently where a casual teacher was provoked and got into a physical altercation with a student that was filmed and widely distributed on the internet, and criminal charges were brought against that teacher. Gun violence not a big a concern in Australia due to much stricter gun laws than in the US -- is this much of a concern over there?
