Well, let's look at Chris's totally unsubstantiated claim that John Lott makes up his figures, shall we?
In his book, "Freedomnomics", we find this section:
It is also clear that legally owning a gun makes a person less likely to get hurt by a criminal. While police are, of course, extremely important in fighting crime, officers almost always arrive at the scene only after a crime has been committed. So what can individuals themselves do to deter criminals? Having a gun, in fact, is by far the most effective course of action.
This is the finding of the US Department of Justice's National Crime Victimization Survey, an annual survey conducted since 1973 of about 77,000 households comprising nearly 134,000 people. This holds true whether the criminal is armed or unarmed and regardless of the location of the attack.
When we go to the endnote notation for this quote and the subsequent specific breakdown, we find this website:
Bureau of Justice Statistics Crime and Victims Statistics
Which does, in fact, contain all the statistics and information that he says it does, and then some. On the other hand, we have merely Chris's assertion that John Lott "makes up his facts", which we are simply supposed to accept at face value. So I think we can all see who is reliable and who isn't on this subject.
