According to California law, what does possession of burglary tools refer to?

Possession of burglary tools, as defined under California Penal Code 466, specifically refers to having tools that are intended for use in committing a burglary. This includes tools that can be used to break into a structure or vehicle, such as crowbars, lockpicks, or other implements designed for unlawful entry. The law emphasizes the intent and purpose behind possessing these tools rather than simply owning tools for general purposes, like construction or personal use.

The other options focus on circumstances that do not align with the legal definition. For instance, tools meant for construction or personal usage do not imply any intent to commit a crime. Additionally, ownership of illegal weapons, while certainly a serious matter, is governed by different statutes and does not overlap with the specific crime of possessing burglary tools. Therefore, the correct choice clearly identifies the specific nature of the offense as it pertains to tools used for the purpose of burglary.
