Comparative Homeland Security By Nadav Morag

British Transport Police work with local police constabularies in emergencies, special training, and overwhelming security demands. When the need arises, local Chief Constables may request assistance from the British transport police. The assistance often happens when local constabularies cannot meet their operational demands, implying that they must be given some support to perform their duties effectively. In essence, the local constabularies should first request aid before the British Transport police can offer assistance.
