"jump ship to the Met "
You're not wrong there, starting with the bloke at the top, who missed out on the top Met job last time round.. My MSP has been raising questions about the fact that a lot of Scottish cops are now routinely armed, even in the Highlands where crime of any kind, let alone violent crime, is the lowest in the UK. Apparently armed cops have been turning up to deal with minor events, a de facto change in the consensual policing that in theory exists. Their response to MSP's questions? "None of your business, mate, we make those decisions." Yup, he seems to want to prove he can up the ante for the Met too.
