The States of Jersey Police serves a resident population of 104,000 people as well as over 700,000 visitors to Jersey each year. The States of Jersey Police currently operates with a funded establishment of 189 police officers and about 100 civilian staff. The high ratio of police officers to civilian staff reflects a practical need to maintain operational resilience. Many officers are trained in specialist skills over and above those needed for their normal duties so that they can be called upon at any time to perform specialist roles. These might include firearms, search, surveillance, siege negotiation, collision investigation, public order, CBRN response and family or sexual offence liaison.
