Should juvenile offenders be tried and punished as adults?

I feel as if you commit the crime then you do the time. It's pretty simple and no tolerance if you asked me. If a juvenile commits a crime and get punished at the full extent of the law then it will decrease the likelyhood of reoccurence. Lots of the juveniles who commit crimes are fully aware of the choices that have made to end up in such a perdicament. In some cases petty crimes should be handle as an adult I would say depending on the juvenile past record. If the juvenile has a lengthy criminal history prior to the crime it means that they obvsiously haven't learned anything yet so handling the juvenile as an adult will most likely open their eyes to reality. When  I say reality not just getting yelled at by their parents,or taking a ride in the police car home but to the adult jail where they would first hand experience what there is to come out of negative behavior.
