Cut -
the middle and upper management first.
Then the targets and bureaucratic reporting requirements.
Then the junkets to 'conferences' in far-away hot places.
Then any post whose title doesn't directly mean "catch the fucking criminals", including Co-ordination Officers; Liaison Officer; Local <insert special interest group name here> Facilitator; any post which keeps a police officer from leaving the warmth and security of the police station / HQ and interacting with the people in the community he's supposed to be working for.
Do these and I reckon that they'll be plods on almost every corner. Rather than every desk in their office.
