Birmingham and Jefferson County are getting some extra help fighting crime. About 100 taxi drivers in Jefferson County have been trained to be on the lookout for suspicious activity. If they see something, they can call police and report it immediately. Yellow Cab announced the new "TOP" or Taxis on Patrol program Monday in front of Birmingham City Hall. The taxis will be equipped with GPS technology that can send and receive information. They will also have security cameras that will be able to help police during investigations.
