Only one in thousands of Americans is really trained in our U.S. Armed Forces to be an effective killer. Pretenders, far outnumbering current and former light combat personnel, imitate civilian police and movie characters (as seen exposing themselves on YouTube).
The many corporate/government executive slobs who have talked about murdering rural families don’t know what they’re talking about, have no related training experience and have shown that they are incapable of realistic tactical planning. Having little hands-on low-tech experience, they’re out of touch with the world around them.
Rural families know their terrain. Every dip, where the ground is soft, which way the ditches run. Things that can't be quickly assessed from an aerial image.
That may well impart an advantage to the defenders.
IF you don't know your neighborhood, rural, suburban, small town, or big city, you should.
