Stuart Parr at Wonko’s World may be onto something here:
The Home Secretary isn’t planning to tell Scottish police forces to merge despite telling us that anything less than 4,000 officers in a police force puts us at risk of terrorism. Obviously this is unacceptable - either there is a risk of terrorism and the Home Secretary is guilty of dereliction of duty or the risk of terrorism is a lie and the merger of police forces is politically motivated.

He’s right. Under the terms of the Scotland Act, policing is a devolved matter. But under that same act, Scottish Parliament can be overridden by Westminster. John Reid claims that the police force mergers that his predecessor was planning are partially to “fight terrorism”. If it’s such a threat to necessitate the merger of the England and Wales police forces, then why isn’t it needed in Scotland? If it is needed in Scotland, why isn’t it going to happen?
