The UK is trying to solve this problem by banning “Ninja swords”.
There was a time when all Englishmen had to appear before the King showing their swords, spears, armor all to show they could be called on to protect the Kingdom from invasion.
ASSIZE OF ARMS it was called. First in 1181 AD. Then several after.
Then in 1920 England got Commie scares and banned the ownership of firearms leading to the plea to the US to “PLEASE SEND A GUN TO DEFEND A BRITISH HOME!” of 1940.
Now England cannot stop a moslem invasion coming in without firing a shot.
It was the confiscation of firearms in the American Colonies that led to the Revolution of 1775.
Now the democrats are trying to do here what their British Masters back then failed to do.
