Actually that "brain stops developing at 25" is a misconception, the study that spawned it just ran out of funding when the subjects were 25 and didn't see the brain development slowing down, iirc (no source on hand it's past midnight here).
25 isn't a hard line. The reality is that our brains continue to change forever. But, to use a metaphor, around our mid 20s is when it's done "cooking", but just like you might let meat "rest" on the counter for a bit after it's done cooking, your brain keeps changing, just not to the same degree. Maybe some day if brain scanning technology gets better, and we have a real healthcare system, people could get scans to see when their brain seems to have reached full maturity, especially if they've committed a crime. Of course "full maturity" will always be sort of an arbitrary choice because as I said, our brains are never truly finished.
