I don't understand why people think someone entering a house to steal should be killed. Since when was the sentence for burglary execution?
It just seems an excuse to blow someone away. If someone plans to enter your house to burlarize it, you feel it is approproprite to kill that person. Whatever the law allows or doesn't allow as far as shooting anyone who enters your home unauthorized, why, as an individual, do you wish to kill the person? Why talk about shooting them through the head or turning their body into Swiss cheese?
For example, why couldn't the guy in the original post have simply fired a warning shot into the sky and warned the kid he was armed? Then lock up his home tight and call the police? Once the supposed burglar knows he has been spotted and that the potential victim is armed, wouldn't it be reasonable to assume he would leg it? Why kill him? And most importantly of all, why do so many posters who say they'd shoot him describe the potential experience of killing an intruder with such pleasure and relish?
