State law defines “lawful entry” as a having either “privileged or licensed” consent to enter a property. If someone enters a property and does not have either of these forms of consent, they are committing simple or criminal trespass, depending on extenuating circumstances.
A person cannot trespass on property open to the public unless doing so would violate a direct lawful order from the property’s owner or a legal authority such as a police officer. Otherwise, that person is assumed to have both license and privilege to travel as they please.
