Theft of Mail Matter is the unlawful taking of mail, either from the mail stream or from a post office. It can be classified into two types: mail theft from the mail stream, and mail theft from a post office. Mail theft from the mail stream involves taking mail that is in the process of delivery, such as from mailboxes, mail slots, or other delivery locations. This type of theft can be committed by an individual or a group. Mail theft from a post office involves stealing mail that has been placed in a post office box or that has been set aside for pickup. This type of theft is usually more difficult to commit due to the presence of security cameras and other security measures in post offices. Both types of mail theft are serious crimes, and can result in fines, jail time, and/or probation. Additionally, individuals convicted of mail theft may be required to pay restitution to the victims for any stolen items or services.
