KCR,

Are you really a juvenile?  Your grammar and writing style kind of give me reason to believe that you have some sort of education beyond high school.

Anyway, here is my advice.  Most juveniles in Texas are tried under the family code which for all intents and purposes is "civil law" as opposed to the criminal law(penal code).  Therefore, I am curious if you have or have not acquired the services of a lawyer, as juveniles quite literally get away with murder.  Also, I have never heard of mandatory periodic Polygraph testing on a juvenile in any State (Texas especially included), another reason I am quite suspicious about you being a juvenile.

What particular juvenile probation department are you refering too?  You don't have to post this, but you can send me a message with it.

Either way, your best bet is to retain the services of a qualified lawyer with experience working in the juvenile system.
