should adult be tried as juvenile in courts

They always talk about putting some minor on trial and pretending he is not a minor, but what about the other way around?  There may be situations where we want to put an adult on trial and pretend that he is a juvenile.

For instance, if he watches Pokemans all day then he might be like that, or maybe he is a pothead since he was 12 and his brain never got older.  Or maybe he only did juvenile crime so he should only do juvenile time, such as spray-painting LOL MY BALLS on a school wall.

No, I mean already we pretend some juvenile is adult for law.  We are allowed to do that pretending apparently, if we just make it in writing.  We can pretend some adult is juvenile then, so let's imagine when.
