This is not aimed at the OP per say.
Getting robbed is a disturbing emotional experience. It sucks. BTDT, got a couple of tee shirts.
One needs to put the emotions in a box and be rational, which is not easy.
Let say someone is stealing your car and one uses deadly force to prevent the theft. If the case goes to court, civil and/or criminal, how long will the value of the car being exceeded by lawyer fees? If the car has insurance and is stolen, even with a high deductible, one will be better off money wise just letting the car go. Not easy on the emotions though.
Back in around 1990 in South FLA, a man came home from work and found a thief stealing his TV set. The thief ran from the apartment with the TV and the owner shot the thief in the back and killed him. State law at the time said one COULD use deadly force to prevent a burglary. In spite of the law, the local DA filed charges against the owner. :confused3: Eventually, the owner was found not guilty but his lawyer bill had to be far in excess of the price of that TV. Heck, I bet I could go to the dump today and the same size or larger TV for free.

Using deadly force for a TV set or a car is just not worth the aggravation. I wonder what the owner would have paid to NOT have to go to court and/or worry about going to prison for decades?
I happened to talk to an officer involved in the investigation. The irony was the pistol the owner used would shoot right, or shoot left, but not straight. The owner was "lucky" to hit the thief and not an innocent bystander.
A few years ago in a rural NC county, an elderly man found a guy trying to drive off in his car. The car owner shot and killed the thief. No way the current law allowed that use of force and I figured the owner was going to get charged and set to prison. There was no legal justification for what he did. However, the local DA did not press charges because he knew he could not get a conviction in the county in spite of the law.
