Actually, it's so that the police can send someone round to shag her first. After the PNC was altered so that any/all checks on women for personal reasons (IE: going round her place after midnight to check her status) were logged (resulting in a large number of early retirements, and a few convictions).
Never attribute a reason for doing something to justice when a base reason is more likely to be accurate.
