When Criminals Face Armed Resistance From Citizens
This is a long read but well worth it. If you need to refute an anti gunner's arguments or wish to sway someone that's undecided then just forward them this link. It has everything needed. I cannot see how any sensible person could read this and still believe in gun control
Basically this is just like the research that I find on the Brady Campaign website except that it has facts, stats, history and truth.
