Thank you for your reply.
marieway,
You're very welcome! 
No, he had no idea at the time that blowing up tree stumps was a crime. The older boy had purchased gunpowder and when the police searched his house, they found evidence there.
The boy had posted this and other incidents on a site called You Tube. He apparently does this kind of thing a lot.
This was my son's first and only time of involvement.
This was considered to be an act of terrorism, as the tree stumps were in federal woods.
If the 'friend' was the one who did everything, and had done it other times prior to the incident involving your son, that's a *clear* indication that your son *wasn't* involved in *any* planning or premeditation! He just *happened* to have been taken along on that *one* particular instance!
The YouTube vids can be considered exculpatory evidence, by the way.
And if this happened on *federal* land, shouldn't it be federal *jurisdiction*? A *county* DA (U.S. District Attorneys are appointed, not elected) shouldn't have the case if it's a federal offense!
The older boy accepted a plea and they waited until my son was 18, then issued the arrest warrant, so despite the fact that he was 17 at the time, this is the way the assistant DA is dealing with it.
My attorney approached her with all our facts and she told him that unless my son had donated a kidney, she was not interested......
Apparently she is up for re-election this year...
I *knew* she had to be up for re-election!
If the 'friend' was 19 at the time the offense occurred, then he could have been charged with 'contributing to the delinquency of a minor'. That your son *wasn't* given the opportunity to plead down that the 'friend' was given could be considered a violation of the Equal Protection clause of the 14th Amendment.
This assistant DA could also be disciplined for prosecutorial misconduct. It's *blatantly* obvious that she's unfairly disregarding mitigating circumstances - the fact that your son is autistic, that the 'friend' had done this numerous times before, etc. - and that she's she's pursuing it on a *malicious* basis, *not* because he had genuinely committed a crime.
We are not looking for charges to be dismissed.
We are looking for his circumstances to be taken into consideration and the charges to be reduced. The other boy, who was 19 at the time, accepted a plea and was convicted of 1 felony charge to be entered as a misdemeanor after 3 years of probation.
Why not dismissed? The only reason that your son is even *in* this mess is because of the 'friend'! The *only* thing he did wrong was *trusting* this kid!
Given the assistant DA's little witch-hunt, it would probably be fairly easy to get a judge to throw it out!
Had the deportation issue not arisen we would have accepted that but as he is 19 and the DA has already contacted INS and alerted them, we have to fight this.
We have mortgaged our house up to the hilt and we will do what needs to be done.
One person who you should *definitely* contact is Senator Ron Wyden; he and his staff should be able to help get things resolved without you having to worry about your son being convicted and/or deported.
Appreciate the advice/help
Thank you
