And what about the kids who get recruited for gang activity and do some pretty messed up stuff as kids? Should that not appear on a public record? This is where the problem lies, you essentially can only ever make it an all or nothing approach as it gets a lot harder to determine what should or shouldn't be apart of a public record. Especially since as you reflected in your comment, this becomes and opinion thing on whether someone thinks it matters or not what crime they did as a kid.

The problem that is happening in most Western countries is that criminal organizations take advantage of the fact that minors get reduced sentenced and that their criminal records are usually kept sealed (unless tried as an adult). Whether it be having them steal cars, partake in organized shoplifting operations, muggings, gang activity, drug dealing, etc...

Your reasoning for why this information shouldn't be public record seems to boil down to the fact that you don't agree with other peoples judgement of someone's past crimes. You'd like to see more forgiveness, and you don't think others will show the same forgiveness, so you want to take away all the access to information because of that. To me that seems like a view from a point of moral superiority.

I'd rather people get access to this information and be able to use their own brains to determine whether they want that person working there. If you were involved in shoplifting at 17 years old, and turn 18, I think it would be very fair for a store owner to be able to use that information to judge you when making a hiring decision. To me it doesn't make sense that you turn a magical age of 18 and suddenly your past poor decisions vanish into a void.

I think we can at least agree that children recruited by organized crime to steal cars, break into homes, assault people, and so on, should be treated differently than a kid who stole a pack of gum from a store. Whatever the solution is, it has to take into account the seriousness of the crime, and it has to discourage this binary criminal / not criminal thinking.
