During lunch at East Ridge High School, Tom Brown is surrounded. "You won’t go through a lunch without three or four kids hanging off our golf cart, talking to us,'' said Brown, a school resource deputy. Most students regard Brown, 60, and Dep. Jason Williams — the other law enforcement officer assigned to the Clermont school — as steady influences. It's a common theme for the 30 men and women assigned by the Lake County Sheriff's Office to serve as school resource deputies (SRDs). They handle security, but that's not all — not by a long shot. When incidents such as what occurred at Eustis High School make headlines, the public could get the wrong impression, said Lt. Christie Mysinger, the school resource commander for the sheriff's office. Deputy Billy Brown used his stun gun to subdue a 15-year-old girl there on Jan. 26 after she struck him several times and they fell to the ground.
