Crime and Punishment

On the one hand you have states like Wisconsin, who send all underage teens to adult jail for almost all crimes, and on the other, you have the current situation in California.

Hanna Tubbs, a 26 year old biological male ( who after being arrested identifies as female ), walked into a rest room and sexually assaulted a 10 year old girl, 8 years ago, when Tubbs was 17 years old.
The LA county DA, has decided in his wisdom, that since Tubbs was a juvenile when he/she committed the crime, he/she will now serve his/her sentence in a juvenile correctional facility, with underage females, even though he/she is now 26 years old.

Am I the only one who sees something wrong with this ?
Is it time for America to have a federally controlled Justice/Penal system, somewhere in the middle of these radical right wing, and left wing, extremes ?
