In a perfect world, Sheets would be free to hunt and kill the burglars at his leisure. Criminals in the commission of a crime should forfeit all protections of the law. Break into a home and steal someones property? Expect to get killed.
I have zero sympathy for criminals and a great deal of sympathy for Sheets.
In the old West, there were outlaws. That is people who did something against the law were outside the law. Simple, yeah. Break the law, become an outlaw, forfeit any protection under the law. Steal a horse, get caught by some law abiding citizens, and swing from a tree. The citizens broke no laws, the hanged guy had no protection, under the law he was a non-entity. Same as a cockroach. Who came up with the idea that an outlaw had rights, that is a horrible misreading of the law.
