When children are tried as adults, they are more likely to lose their freedom at such a young age and are exposed to a terrifying, harsh environment in adult prison. Research studies have shown that juveniles recidivate at a much higher rate when released from adult prison than when they are released from a juvenile detention center. Although children account for 1% of the adult prison population, they account for 21% of the reported sexual assault cases within prison. These children are serving out their sentence next to child molesters and predators who were jailed in the first place to keep them away from children. Adult prisons do not have the resources of the funding to provide the nutritional and medical needs that juveniles require as they continue to grow. Some are placed on a 23 hour lockdown to try and protect them from the rest of the prison population. This creates many mental health hazards, and contributes to many juvenile suicides while in adult prison. Children are 36 times more likely to commit suicide in adult prison than a juvenile detention center. Each state has different laws for when they send children to adult court. Some are age laws, others vary by the condition of the crime, but children as young as 10 have been sentenced to life behind bars. Some states are trying to reform their laws to keep juveniles in the juvenile justice system. Either way, juveniles need to remain in the juvenile justice system to protect their physical and mental health, as well as giving them a better chance at rehabilitation for the crime they committed.
I think this all depends on the seriousness of the crime e.g. the story of Jon Venables and his friend. Basically two 10 year old boys did unspeakable things to a toddler before throwing him in front of a train. If a child can commit this atrocity then I think others can too and you hear so much of kids shooting their parent over stupid things such as taking away their games console. If a child can do this at that age they must have some serious problems, if a dog did this at a young age it would be put down as its known that having a history of violence dramatically increases the chances of re-occurrence. Also please can you confirm what you regard as a minor as we have different laws here in the UK
