An aspect of self defense in one's home that isn't discussed much is revenge. Robert Wallace of Wheat Ridge, Colorado had his 15 minutes of fame when he was charged with 4 counts of attempted murder for firing two shots at two criminals stealing his trailer parked in his yard. Eventually the courts decided not to send an 82 year old man off to the Big House for the rest of his life. They decided that probation would be enough, but took all his guns away from him. Society is safe and justice is served.
Now, his RV has been purposely burned by someone. It appears someone climbed the ladder, poured gas or some combustible into the roof vent and tossed a match. He believes it is revenge and that is a pretty good guess since the police have said the thieves he shot at belonged to a car theft ring. When we defend our home, any surviving bad guys are pretty upset. We have increased the risk of their chosen profession. Clearly we must be punished. The survivors or their confederates know exactly where you live, and after the news coverage of the shooting is done, they know lots about the person who defended his home. This is bad, but not as bad as doing nothing when your home is invaded. In the case of Mr. Wallace, he has angered someone willing to do violence to property and perhaps more. The government has disarmed him to protect society. Who protects Mr. Wallace?
