Here is a link to an article by John Lott that illustrates the despicable tactics of the anti-gunners.
Lott is on target, it is worse than he portrays.
The best book on the impact of concealed carry and related laws on crime rates is Lott's "More Guns Less Crime". It provides all the common sense, statistics, and description about the level of discourse by anti-gunners that you need. On top of that, it is a great read.
