A graduation ceremony for a new Alabama Law Enforcement Agency state trooper class took place Thursday. It is the first state trooper class since 2010. Twenty-one officers finished classes at a state training center in Selma. The agency says 289 troopers were assigned to highway patrol last year, far less than the 871 officers suggested by a University of Alabama study. With the graduation and personnel shifts, the department says 419 troopers are now available to patrol state highways.
