Bentley signed the order Tuesday, which makes state Homeland Security Director Spencer Collier the state's senior law enforcement adviser.
One of Collier's responsibilities will be to ensure the maximum number of state law enforcement officers are on the streets. The governor says consolidating administrative duties among departments is a way to accomplish that.
Bentley says his plan would consolidate some administrative functions such as purchasing, fleet maintenance and communications.
Competing plans are being developed for achieving more efficiency in Alabama's law enforcement operations.
Senate President Pro Tem Del Marsh unveiled legislation Friday that would consolidate and reorganize the state's many law enforcement functions into a new Public Safety Agency. It would include state troopers, the Alabama Bureau of Investigation, marine police, the fire marshal and others. It would abolish the state Department of Homeland Security and divide its duties among other agencies.
