Lott is also the guy who predicted that Australia would become a lawless wild west with stricter gun laws in place after the Port Arthur massacre. He overlooked the point that we never really had guns anyway, and the laws were only restricting automatic rifles and requiring guns safes at home, and that after a one year slight rise in crime (crime is cyclic), crime has dropped markedly since that point (for reasons entirely unrelated to guns, because guns don't really factor into our society).
This wouldn't be so much of a big point, except that he did spend a lot of time trumpeting about this single year of slight rise in crime. If you read his studies at the time, he also grossly misrepresents things like doing that trick where you report going from 4 to 5 incidents a year as "OMG! 25% increase!" (can't remember the exact number)
Kleck is another guy with crazy stats. In one report he
mentioned that concealed handguns saved 230k lives per year in the US. I crunched the numbers to see how that would translate to our 'lawless', 'gunless' country, where criminals 'have free reign', and it would mean we would have 15k deaths because we don't do concealed gun laws. Turned out that our annual murder rate from all sources combined is about 300. Part of the pro-gun propaganda is the implicit assumption that every crime involves death or rape.
I've spent a lot of time looking at gun issues over the years and started out from a total anti-gun perspective, with the exception of farmers and security. As I've examined it, the problem really seems to be handguns. Rifles don't seem to be so much of an issue - anecdotally at least, it's hard to conceal a rifle. The armed Swiss that's so often reported are armed with rifles, too (interestingly the 'armed society is a polite society' people always seem to leave out west Africa...). When you start looking at the statistics in the US, it really jumps out at you how bad handguns are there. I've also never, ever, seen any pro-gun argument make note of the role of the startling increase in US incarceration have an affect on crime rates. It's an interesting topic and blinkered passion rise on all sides, that's for sure.
