Well, here we go

I am a relatively new teacher. First year, so I currently have about 6.5 months experience. My musing, and discussion for now, is this:  What are your opinions on security in schools in your area? I live in Mobile Al, and currently the school I work at has a pretty open campus. There is a fence around it, but it is not closed during school days, and the gaps between the iron bars at the front of the school are such that a kid can easily slip through them. The doors are open, we have a resource officer, but there is only one person.  What is it like where you teach? What do you think should be changed, in light of recent events in schools?  Do you support arming teachers?
