What term describes a person who enters or remains in a place knowing they are not licensed to do so for the purpose of threatening others?

The term that accurately describes a person who enters or remains in a place knowing they are not licensed to do so for the purpose of threatening others is known as a criminal trespasser. This designation emphasizes the illegal nature of their presence, as it involves knowingly entering a property without the owner's permission, especially with the intent to threaten individuals present there.

A criminal trespasser not only violates the property rights of the owner but also adds a layer of menace by intending to threaten others, which can elevate the seriousness of the offense. This distinction is vital in law enforcement and legal contexts, as it underscores both the unlawful entry and the intent behind the action, which may lead to further legal ramifications.

Simple trespasser might imply an unlawful entry without the added threat or malicious intent, which doesn't capture the full severity of the actions described in the question. Burglary involves entering a building unlawfully with the intent to commit a crime, but it typically refers to theft or similar crimes rather than simply threatening individuals. Criminal mischief refers to damaging property, which also doesn’t align with the context provided regarding threats to people.
