I my self am in the teaching industry and I see all this children on a day to day basis. It is devastating to see all these things going on in the world specially shooting and killing innocent people. All we could do is just be aware of our surroundings and try to be as safe as we can maybe even encouraging the teachers to leave the rooms open when it’s recess in case of an emergency or having more police officers out there on the look of schools and try to avoid all these things. In reality there’s not much we could do unfortunately as a supervisor for children all we can do is be aware having more areas where we could gather children faster or having a go to plan in case something like this happens again.
