That's not what she asked. You may or may not know (by reading couture notes in your newspaper or calling the DA) what the punishment was even if the can't tell you the identity of the minor - if, indeed, the thief actually was a minor not already known to you.
A stolen car would never make the papers. Especially if it was returned. If the PARENTS felt like telling me what punishment the thief got, that'd be nice. But I don't believe they're obliged to. And I've never heard of a D.A. that was willing to violate the confidentiality rights of a minor child.
Mama Who asked specifically "If a guy steals your car and you get it back, do you consider justice served because he no longer has your car?"
You didn't answer her question. If a person of any age stole anything from you, would you consider justice served simply because you got the item back?
I'd say it depends.
What if it's a rocking chair or planter from your front porch?
Yes, definitely, I'd be happy to just have my chair and/or planter back! I'd hate to see a kid strung up and pilloried over a planter. This one I'll be happy to leave in the hands of the parents, and NO, they have no obligation to tell me what they're doing to punish the child.
How about a bag of groceries while you're unloading your cart into your car at the supermarket?
Yeah, that's happened to me, and not only was the thief never caught, but I never got my groceries back. If I could get my groceries back, I wouldn't really care if the thief got away.
Your coat from a bed at a friend's party or an unmanned coatroom at a function hall?
Depends on the circumstance. IF the thief was a child and all my belongings were returned, then I'd turn the matter over to their parents.
Your homework/paper/test?
It's a matter for the principal and the parents of the child. I may find out through the grapevine, but I don't expect an official report.
The credit for the major project you did at work?
How would a child steal the credit for a major project I did at work? It's a different matter when adults are involved. Too many variables here anyway. Is there a union? Is it a big company or a small business? Do I have a personal relationship with this person?
That's a matter for the police. Can't have an underage driver joyriding in my car.
Ah, now finally here's something serious. Identity theft cannot be "returned". Once your information is out there, it's out there forever. So this is actual permanent harm done, unlike all your other scenarios in which the item is returned undamaged. It's a matter for the police. And I'll be too busy trying to repair the damage to wonder what happened to the minor who did it.
What, a child has kidnapped my child???

Clearly another matter for the police.
You get the object or the grade or the credit or the person (forget about your identity - that's going to take ages to fix, if it's ever completely resolved) back - so all is forgiven? That's a genuinely great attitude, but I have a hard time believing anyone would actually react like that in the victim's shoes.
I've had things stolen from me before. When my groceries were taken, I was annoyed, but I decided to view it as an involuntary donation to the poor (or mentally disturbed).
My husband's car was broken into and rifled through and we lost a jackknife. We counted our lucky stars that the car's locks weren't damaged and we had nothing more valuable in there. We reported it to the cops in case they were keeping tabs on that sort of thing, and then we let it go. We never heard anything more about it, and we're fine with that.
My neighbour's house was broken into and while the cops were kind enough to tell her that it was "kids" that did it, we never found out who they were or what happened to them. She spent the next year dealing with her insurance company to get everything fixed and replaced.
I'm not one for holding grudges. It's a waste of my energy. And I'm not interested in parenting other people's children either.
So YES, I would and have actually reacted like that.
Gotta tell ya, I was held up at knifepoint once. I got back everything except the $10 or so in my wallet. That didn't make me feel ANY more compassionate toward my attacker, and it truly wasn't about the money.
Seriously? You're comparing a switched name on a paper to being HELD UP at KNIFE POINT? I have every sympathy for the trauma you've gone through, but that's like comparing a nasty comment to a death threat made at gunpoint and saying they're the same thing.
You're avoiding the actual question and pardon me if I do not believe that you'd really be hung up on WHY he stole your car. I have trouble believing that you'd shrug and walk off and think it was punishment enough that he didn't get to keep your car.
I'm saying, just like the OP, I'll never know whether he was punished or not.
