English police are not, normally, armed (about 5-10% of them are authorized to be armed, according to the police union there).
As compared to that, having everyone be armed would be expanded police authority.
Arm them with spitballs. Is that OK?
I don't care what the ***** Bobbies do.
The Brits have plenty of problems with lots more than just their semia-armed Bobbies.
I say leave 'em alone and see how long it takes for the UK to sink into the North Sea.
