The judge recomended boot camp,so in this particular case the judge will not reverse his sentence it is now in the hands of the prison if they won't comply to the judges wishe's then he will have to stay where he is.

Well it depends on where are you trying to enroll him, try some searches and analyze which program/boot camps is suitable and make sure Which type of boot camp enroll such a teen. While Brat camps are very similar to wilderness programs and some of them closely resemble the juvenile boot camps that have grown in popularity. Brat camps are considered by many to be good options for teens that have early signs of problems but have not become firmly attached to negative influences and bad behavior. However, teens that have developed bad habits over long period of time would benefit more from long-term options that range from 12-18 months. Long-term options have the ability to replace bad habits with positive, constructive habits that will benefit the teen throughout their lives.
