In all seriousness, are you just making up rules to justify how you feel emotionally?
I'm in the law which why I know you're just throwing shit at the wall hoping something sticks, lol.
1) When kids are caught joyriding their parents car, they ask the parents if they want to press charges. If the parents say no, it is not treated as stolen. Because for the item to be stolen, the thief has to intend to deprive the owner of the item. And most kids aren't intending to deprive their parents of the family vehicle permanently.
As for "I know a case....", spare me the random anecdotes. We live in a nation of laws. There are random anecdotes for every potential story. But even then your anecdote doesn't have any jail time...so what is the point.
