Policing in Scotland has evolved over the last five years. Prior to April 2013, there were 10 police bodies providing services across different regions of Scotland. These were different organizations with different infrastructures and different values. They also had differing expenses and budgets. Each service had its own computer systems, chief officer teams, and specialist services. The opportunity to bring these different organizations together into a single police service was realized on April 1, 2013, when Police Scotland was established.
