What constitutes possession of burglar's tools?

Possession of burglar's tools refers specifically to having tools that are intended for use in the act of breaking and entering or committing theft, without a legitimate reason for being in possession of those tools. The emphasis is on the intent behind possessing the tools; if someone is found with tools that can be used for trespassing or burglary, and there is no lawful reason for having them—for instance, not being engaged in a legal occupation that requires such tools—it can indicate the intention to commit a crime.

In contrast, owning tools for home improvement, using tools for personal projects, or collecting antique tools for display do not involve the malicious intent or potential criminal activity associated with burglar’s tools. These activities are generally legal and do not imply an intention to engage in property crimes. Thus, the key factor in determining possession of burglar's tools revolves around the tools' intended use and the lack of lawful justification for possessing them in that context.
