Hire a lawyer.
Legal disclaimer: The statement above is general in nature, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship.
The police are not your friends and they are not out to help you. They are out to build a case that will stand up in court, especially by getting you to confess. Even though the amount you allegedly stole is small, a criminal conviction for shoplifting is a crime of moral turpitude (a crime involving dishonesty), and could have serious immigration consequences, depending on your immigration status. You will need to hire a criminal defense attorney who is familiar with immigration matters. If this is your first offense, a criminal lawyer could perhaps get the case taken care of in a way that won't result in your having a criminal record. So, in short, hire an attorney, don't discuss the case further with anyone but him or her, and don't talk to the police.
