Same for Gwinnett. The issue lies around the definition of the qualitative term "serious". [ or is that "series?" ] Personally, I think the 4300 +/- number correctly reflects the 'threat' environment.
Personally, I think the 4300 +/- number correctly reflects the 'threat' environment. You're probably right, and while I don't know anything about the various Gwinnett schools, I'd bet that most of the 'threats' are at high school level, and there are a lot more 'threats' at some high schools than others.
