Some questions, probably best aimed at those on the other side of the pond;
what are the numbers, if recorded at all, for (1) the number of crimes prevented because an intended victim, or possibly an immediate bystander, had a gun, and at least threatened to use it ; (2) the number of 'perps' shot under these circumstances; (3) the number of uninvolved people injured or killed in the crossfire, ( collateral damage ? ), when somebody draws a gun and defends themselves from a crime, or perceived crime.
