I don't think that it's a show of hubris and bravado to point out that you would prefer to confront the criminal rather than retreat further into your own home and hope for a merciful crime. If he stole your TV, not THAT bad... but like others have pointed out, what if he's after more than a valuable item or two? The factors and conditions go on and on. The law may want you to hide and wait to be rescued. Protecting you, your loved ones, and your property may demand that you take immediate and decisive action. I too have heard the saying
"better judged by twelve than carried by six" and I definitely agree with it.
It's not a "I would do this if", it's more an issue of law and the right to live and live safely. The law is there for you usually... sometimes it isn't. The government is bigger than you... you won that fight but lost that "war" so to speak... I feel sorry for the student, I bet he was just doing what he thought necessary. Perhaps if he was a single father with a little girl or a young woman he might get into less or no trouble. Such is law.
