I have insurance for my physical possessions, and am more than willing to defend my family's lives and limbs. Although I'm quite ready to do so, I am not so psyched by my inflated bravado that I'll adopt a "if it moves, it's dead" strategy. There's a split-second in there where I'm going to identify my threat, or even if it exists, before I go Rambo on somebody. If they're leaving with a VCR, they need it worse than I do, because my insurance policy will buy me a nicer one. That may rub the Texicans in here raw, but I ain't a Texican, and cattle rustlin' ain't in my local laws, anyway. As one of our resident and usually well-grounded Texicans, Art referenced the "time spent" argument as he borrowed it from THR, but I doubt even he would consider ending one's remaining lifetime of hours for the few hours of work spent to originally buy the stolen widget - not entirely proportional, is it? Regardless, the Texas deadly force/property law is the exception, rather than the rule, and one cannot use that measuring stick in the remaining 49 states that comprise the membership here. A DA would have a very easy case in that respect.
In my case, with my insurance, they could steal my VCR, DVD player, and TV and I still might as well not bother reporting it to my insurance, as the depreciated value of 5+ year old electronics is pretty much zilch. Still, they meet my needs, so I wouldn't sell them for the price I could get for them - they have more personal value to me than their book value.
Then there's the philosophical part: they start with your VCR, but they're never satisfied - they keep stealing. If not from you, from others. To support their drug/gambling habits. So they steal an item worth $200 to you, $100 on the books, for $50 or even $20 at a lenient pawn shop or whatever. They cause damage - ransacking your home, breaking locks, doors, furniture in their search for valuables. It costs the time of the police and insurance adjuster. Sure you have 'insurance' for it. Now think about how much lower your insurance premiums could be if we didn't have burglars running around.
The cost to society of these goblins, even if they don't move up, is enormous.
Sure, I have replacement value insurance - but I still have a $500 deducible, which is about a week's income after deductions. Plus I currently pay ~3 weeks of pay/year for my insurance. Without criminals it could be a bit lower.
