If you could get every anti in the United States to read this 55-page law review article, I think it would probably convince a substantial percentage of them to rethink their efforts. The author makes a great effort to demonstrate the inherent practical problems in current gun control legislation caused by defiance of those laws and the sheer number of firearms available in our society.

It is worth reading in general just for the tremendous amount of good information contained within; however it is particularly worth reading if you debate with antis on this subject. It has a number of arguments that explain why even if their goals are something we wanted, their approach is not one that will succeed.
