The right to bear arms is written into US constitution. If your country has no such right, that is what it.

If you have rights and they are written in a contract with the people of your nation you should respect those contracts with the people enough to know those rights are substantial. You should never yield up any of your rights for the so-called common good.

Historically, enforcement of law was never a problem in Britain. The ultimate authority is based in the reprisal of the law, so to speak. It doesn't matter if a Bobbie had a gun, authorities for centuries have put criminals into dreadful prisons, made indentured servants out them, put them into the tower...etc. An accusation was enough to make the worst of the lot tremble.

Nowadays, liberal and so-called equitable treatment of criminals with lesser punishments will require Bobbie to have a gun or he'll get wasted.
When the authority and enforcement of law at the highest levels is compromised the tougher it will be for the man on the street.

Fact is... you will see more Bobbie with guns. Only when criminal punishments becomes extremely severe will you see a casual policeman walking and whistling along the lane, swinging his club like a band leaders baton.
