I think Nashwan has covered the stats. Gun crimes are up, but the report says that a crime is sometimes committed even if a gun is not fired - eg. used to threaten - that is still a gun crime.
I have seen folks point to "a 20% increase in Britain's gun homicides since the 1997 ban" (not in this particular thread, but in one of the many others) and seize upon this in a limpwristed attempt to make a "point" and citing it as a "trend", when in fact all we have seen is year on year fluctuations - an increase from 50 to 60, for example. However bad Britain's gun crime record is right now, it's still minute when compared to the US, and is much too small for an adequate level of sampling data to be available to determine a trend.
And as Nashwan points out, you can slice it, dice it, splice it, spin it, but whichever way you cut it, 147 times as many people were victims of firearms homicide in the US as here.
But this is off topic! My original point in this thread was to express my observation that the more guns we have in Britain, the more gun crime we'll have. No need to examine the relationship in any more depth.
We can already see what happens to the homicide rate when a country is flooded with guns. Well, at least some of us can. I guess others never will.
