With disruptive behavior on the rise at some Montgomery County libraries, some officials say they might start throwing the book at youthful violators.

At least 43 “disruptive” incidents were reported by library staffs across Montgomery’s 22 branches through August this year, according to a county report. Those incidents, which county officials say are largely the result of youthful violators, include disorderly conduct, verbal abuse, fighting and sexual misconduct. No serious injuries have been reported, county spokesman Neil Greenberger said.
