The UK government can’t wait to order the cops and military to kill any revolting peasants. And the cops and military will cheerfully do it.
The cops and military would have to become the source for peasant’s arms (unless they can find muslim stashes). Their taxes paid for them anyway. Not many cops in the UK are armed. Only certain cops are authorized to be armed. The exception is Northern Ireland where it seems most cops are armed, or authorized to be armed.
