Life in prison for Juveniles?

If a juvenile that is 17 years old and is charged with a first-degree murder, should the law send him to juve or should they lower the cut-off age of the juvenile courts to 16 or 15, try him in an adult coourt and sentence him to life in prison without parole at the age of 17? Sending a miner to life of prison without parole seems kind of harsh. No kid should be in an adult prison for life. If the crime was that intence than at least do the 30 years thing or something. Even if the crime rate did lower in the 90's, it is rising again because the youth thing that it is to harsh.
