DeSoto County; authorize sheriff to use radar on county roads.

HB 4100 authorizes DeSoto County's Board of Supervisors to purchase radar speed detection equipment for the sheriff's department to enforce speed limits on county roads and state highways outside incorporated city limits. It requires that any fines collected from speeding violations detected by this radar must fund school resource officers in DeSoto County public schools. The bill directly affects drivers on these county roads, the sheriff's department (which gains enforcement tools), and the county's public schools (which receive dedicated funding). This is a concrete policy change redirecting traffic fine revenue to school safety resources within DeSoto County.
