Must a police officer always advise a person of their Miranda rights before asking a question?
No. The Miranda warning is only in effect during a custodial interrogation. This means that the person being questioned is in custody or in an environment in which the person does not believe that he is free to leave.
For example: Officer Jones is investigating a robbery at the local supermarket. The cashier indicates that a patron named Mary Smith may have seen the robber. When Officer Jones interviews Mary, Mary makes statements implicating herself in the robbery as a lookout. Can Mary`s statements be used against her later, even though she was not read her Miranda Warning? The answer is yes, because Mary was not in custody when she was being asked the questions. Therefore, Mary was free to leave if she wanted to.

What happens at an arraignment?
You have the right to be arraigned without unnecessary delay - usually within two court days - after being arrested. You will appear before a judge who will tell you officially of the charges against you at your first arraignment. At the arraignment, an attorney may be appointed for you if you cannot afford one, and bail can be raised or lowered. You also can ask to be released on personal recognizance, even if bail was previously set.
If you are charged with a misdemeanor, you can plead guilty or not guilty at the arraignment. Or, if the court approves, you can plead nolo contendere, meaning that you will not contest the charges. Legally, this is the same as a guilty plea, but it cannot be used against you in a non-criminal case.

Before pleading guilty to some first time offenses, such as drug possession in small amounts for personal use, you may want to find out if your county has any drug diversion programs. Under these programs, instead of fining you or sending you to jail, the court may order you to get counseling which can result in dismissal of the charges if you complete the counseling.

If misdemeanor charges are not dropped, a trial will be held later in county court of law. If you are charged with a felony, however, and the charges are not dismissed, the next step is a preliminary hearing.

What is bail?
Bail is money or other property that is deposited with the court to ensure that the person accused will return to court when he or she is required to do so. If the defendant returns to court as required, the bail will be returned at the end of the case, even if the defendant is ultimately convicted. However, if the defendant does not come to court when required or violates his or her bail conditions, the bail will be forfeited to the court and will not be returned.
