Thank you for your question. I look forward to working with you to provide you the information you are seeking.
The law does not require his parent to be present when he is being questioned, BUT the law DOES required that before the officer can question him the officer must advise him of his Miranda Rights. Any statement or confession made based on the questioning of the officer without informing the minor of their rights under Miranda would be subject to being inadmissible in court and your son's attorney would argue the statement must be suppressed or thrown out and as such without such statement from your child, there are no witnesses or evidence to show your child committed this act.
I truly aim to please you as a customer, but please keep in mind that I do not know what you already know or don't know, or with what you need help, unless you tell me. Please consider that I am answering the question or question that is posed in your posting based upon my reading of your post and sometimes misunderstandings can occur. If I did not answer the question you thought you were asking, please respond with the specific question you wanted answered.
Kindly remember the ONLY WAY experts receive any credit at all for spending time with customers is if you click on OK, GOOD or EXCELLENT SERVICE even though you have made a deposit or are a subscription customer. YOU MUST COMPLETE THE RATING FOR THE EXPERT TO RECEIVE ANY CREDIT, if not the site keeps your money on deposit.
Also remember, sometimes the law does not support what we want it to support, but that is not the fault of the person answering the question, so please be courteous.
