The GM used info in his opening post that's really contradictory to what he's saying now. Furthermore, several PCs are straight up carrying knives around (at school, no less), which escalates the general seriousness of the situation. There's no reason not to include older characters unless you've got a seriously good reason. Even high school punks bother elders all the time.
