According to CPL section 2.20, why might peace officers take custody of firearms not owned by them?

The correct answer reflects the legal authority peace officers have to take custody of firearms as part of their responsibilities to ensure public safety and compliance with laws. When firearms are not owned by them, peace officers may take custody to dispose of them legally. This is often necessary in situations where the firearms are found to be abandoned, illegal, or in the possession of individuals who should not have them, such as those involved in criminal activity or who are deemed a threat to themselves or others.

Disposal must be done in a manner that adheres to laws governing firearms, ensuring that they do not return to illegal circulation and are handled according to regulations. This promotes community safety and upholds legal standards regarding firearm possession.

The other options suggest uses for the firearms that do not align with the legal and ethical obligations of peace officers. For example, using firearms in investigations or for personal use would raise serious concerns regarding legality and integrity, and selling them would represent a significant breach of protocol and law, diverting from their intended purpose of maintaining law and order.
