Some people choose to employ private security guards, some of whom are armed. This reflects distrust of the police’s ability to provide security and a fear of crime.
Armed security guards are subject to the law, in the same way that the police are, but they may not have had the same level of training – so they put the public at risk. George Zimmerman, who killed Trayvon Martin in the incident referred to earlier (7.2.3), was described as a “neighborhood watch captain” – highlighting the difference between an American armed watch and the British concept of neighbours being vigilant (188.8.131.52).
The most dangerous form of ‘self-service’ in policing is the formation of vigilante groups or militias. Some militias, which are created by ethnic groups to protect themselves, provide a ready means of escalating tensions into more serious violence – such as that which occurred during the partition of India (184.108.40.206).
