The acts of breaking and entering a building were historically part of the definition of the crime of burglary. But most states have since broadened the definition of burglary to include any entry into a building without the permission of the owner and with the intent to commit a theft, assault, or other crime inside the building. But a few states still have a distinct criminal offense of breaking and entering a building.

And some states have a similar criminal offense of forcible and unlawful entry that make it a crime to force entry into an automobile, safe, ATM, parking meter, or vending machine.

Breaking and entering laws (and related property crime laws) are usually located in a state’s penal or criminal code (statutes).

In Oklahoma, the crime of burglary is defined under the state's penal code and has been expanded from its historical definition. Oklahoma law considers burglary to be unlawfully entering a building or a part thereof with the intent to commit a crime therein, regardless of the time of day. This includes breaking and entering with the intent to steal or commit any felony. Oklahoma statutes also define separate offenses for breaking and entering without permission, even without the intent to commit a crime inside. Additionally, Oklahoma law criminalizes the unlawful breaking into vehicles, coin machines, and other property with the intent to steal or commit a felony. These laws are designed to protect property rights and maintain public order by deterring unauthorized entry and potential subsequent criminal activity.
