Final answer:
The determination of guilt for first-degree burglary depends on various factors, including the jurisdiction's laws, the intent of the entry, and the nature of the building.
Step-by-step explanation:
Whether one is guilty of first-degree burglary by entering a locked office building at nighttime depends on the jurisdiction's specific laws regarding burglary. In many places, first-degree burglary is defined as the unlawful entry into a building with the intent to commit a felony, theft, or some type of crime once inside, typically involving an inhabited dwelling rather than an office building.
However, the severity can be higher if the burglary occurs at night. To be charged with first-degree burglary, factors such as the time of the crime, the nature of the building, the intent of the entry, and whether the building was inhabited are critical.
