If you can't defend yourself, your family or your property, without fear of prosecution, then humanity will continue to fail, and the criminals will ALWAYS win...!!!
If criminals continue to get away with committing crimes, then obviously they will continue committing crimes....!!!
If punishment is swift and very severe, then only the stupidest criminals will continue to commit crimes, and if they continue committing crimes and get caught, then locking them up for a very long time will solve many problems...!
If this criminal gets beat up for breaking the law, and if he didn't go to hospital quick enough after being beaten up while committing a crime, AND if he refused to be fed through a tube to help save his life, then HE is responsible for his own death...!!!
