Tackle him while he's reloading! http://www.youtube.com/watch?v=QWmCQ_9Gm-I Looks like the most effective defense is to limit the size of magazines.
Returning fire also works an this way you won't have to dodge a full clip. You can also live in a republican district instead of a democrat one, they are much safer. Far less murder. Dems are 8 times more likely to murder after all.
I personally prefer Kid Rock's approach. Thank God I was not on the property at the time of this attempted break in, I am an avid hunter and marksman and I will not hesitate to shoot anyone who has myself or family in fear for our lives.
