If you look at crime in the UK, Gun crime (In most crime committed) is negligible and changing the law to allow everyone to have a gun will just cause more criminals to buy one, AND be prepared to use it.
This is the last thing you want, as it just moves crime up to a whole new level where a Tyros 3 becomes more valuable than a human life.
In the States they have always had guns all through their history, whereas in the UK they haven’t, so how crime is tackled in one country, cannot be transferred to another.
