Britons are free to live without the constant threat of being murdered by a gun, either by a criminal or a thuggish policeman.
Such as the people killed a few days ago by the taxi driver? Sure their murder rate is lower, but I'm not sold on the idea that guns/murder rate is the only relevant corelation.
The difference is that in Britain the shooting is a noteworthy and unusual occurrence that's made the national news. People being killed in a drive by shooting is a normal happening in this country, grimly reported on the evening local news every few days and then quickly forgotten.
