I posted this for two reasons:
1) It is an example of why we should not let our guard down. These thugs could have just as easily waited to ambush their victims in the parking lot, rather than shooting into their home. Fortunately for the victims, they were attacked in their castle, where they could possess their arms without fear of persecution or prosecution.
2) It illustrates media bias. Would anybody disagree with me if I accused CBS of trying to push the "wild west" angle of anti-gun sentiment? They may have no motive further than grabbing the viewers' attention - more clicks means more ad revenue, after all. Of course, they could also have the motive of an anti-gun agenda at the same time.
