You're exactly right. There are many repeat, habitual offenders -- problem kids, go figure.

In our school system, a student may be expelled after one very serious offense. Serious offenses may also result in the student being sent to an alternative school, as may 10 or more less serious offenses - but in the alternative school, they are still in the public school system, just not in the same setting as the other students.

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.
