It depends on their age and offence. If a teenager commits murder - try as an adult. They are old enough to know what they are doing, and that it is wrong. Nothing 'magical' happens when they turn 18, they don't suddenly aquire a sence of right and wrong. (sorry, getting on my soap box...stepping off now) But on the other hand, if a kid makes a mistake, they should be given the opportunity to learn from it and move on with their life - unless there are circumstances that would dictate otherwise. -- Short answer? It depends.
Only if they are being tried as adults; otherwise, juveniles lack a few of the due process rights established in the US Constitution, such as the right to a trial by jury and the opportunity to be released on bail. Some states provide juveniles the option of a jury trial under specific circumstances.
On the other hand, juveniles receive special protection not applicable to adults, such as greater privacy and confidentiality, and exemption from capital punishment and sentences of life without possibility of parole. Many young offenders are also able to have their juvenile records cleared or sealed after they turn 21.
The States who do that evidently think so. The general opinion in the Western world however is a) that juveniles are still in a phase of their mental development where they cannot be fully held responsible for their actions and b) the first priority with juvenile delinquents should be to try and set them straight and give them a chance to still make something of their lives.
So almost all Western and also many Third World countries think that sentencing juveniles as adults is unethical, with exceptions only being made when delinquents were already practically adults at the time they committed their crime and if their actions are considered to be highly and coolly premeditated.
So they won't do it as an adult.
No
There is no comparison to be made. Juveniles are juveniles and the law says they should be treated differently from adults, regardless of the charge against them.
to what extent should they be treated as adults
Laws vary by state, and depending on what the crime was, but in general, yes, juveniles can be tried as adults if the juvenile court certifies them as an adult and transfers the case to criminal court.
Juvenile because juveniles aren't charged as badly as adults.
Well, If
Juveniles (supposedly) lack the maturity to understand the wrongness of their actions. Hence, punishment is lighter, so they are educated in consequences without having their life unduly ruined by a simple mistake.
I think they are housed in adult jail and prison
Yes they should they should be arrested
Of course they can. They generally are barring some juveniles.
The likely word is the plural noun "juveniles" (non-adults, or teenagers).
The best way is to not commit a crime.
Yes, juveniles have a constitutional right to a speedy trial under the Sixth Amendment of the U.S. Constitution. This right ensures that juvenile defendants are promptly brought to trial and prevents undue delays in the legal process.
