My question involves criminal law for the state of: Michigan
My adult son is charged with felony trespassing in a key facility 750.552c. (imprisonment not more than 4 years, fine not more than $2,500)
He was appointed an attorney by the court. We met with this attorney for a few minutes prior to his first hearing. The appointed attorney recommended my son waive pre-trial hearing (he did). The attorney also indicated that my son was offered a plea agreement--plead guilty to the felony charge, receive probation (of unspecified duration), once he completes probation, he can petition for the charge to be reduced to a misdemeanor with "no opposition from the people." Attorney also said the circumstances (in part, mental health issues stemming from a violent mugging several years previously) leading to the incident (in which he was severely injured) do not matter because it is a "general intent" crime rather than "specific intent."
My son has another court date next week. I'm not sure exactly what this one is. I'm not familiar with legal proceedings. He has not spoken with his attorney since the original court date last month and was never asked anything about the offered plea bargain (accept? decline?).
My questions are:
Does this general intent VS specific intent really mean it doesn't matter that he didn't intend to trespass/cause damage? Even though the first words of the code state, "A person shall not intentionally..." He was there, therefore he is guilty? (this last was the reason the attorney recommended waiving pre-trial--no question he was there)
In regard to the plea bargain, should he have been asked whether he accepted or declined at the time it was mentioned or will it be brought up again? Is it ever possible to negotiate further? If he pleads guilty to a felony, does he carry that label during the term of probation? If so, he would likely lose his job, which requires him to be bonded. If it is possible/acceptable to negotiate, how is that handled? Does my son just tell his attorney he is willing to plead guilty to a misdemeanor up front for probation (suggested by a friend who is an attorney) before this hearing on Monday?
Thank you for any information.
