Which of the following incidents would NOT be classified as burglary?

Burglary is typically defined as unlawfully entering a structure with the intent to commit a crime inside, often theft. The key component is the unlawful entry into a building or dwelling.

The option that indicates casually entering a public space and stealing does not fit the legal definition of burglary. In this scenario, since the space is a public one and possibly open to the general public, there is no unlawful entry involved. Burglary specifically requires an unauthorized entry into a secure area, which distinguishes it from theft occurring in a public area.

In contrast, the other options involve scenarios where unauthorized entry into a building occurs, thereby making them fall under the definition of burglary. These include actions taken to enter a space (whether through force or other means) with the intent to commit a crime within, clearly aligning with burglary criteria.
