Final answer:
The question pertains to law enforcement procedures regarding the number of cartridges an officer should carry for a CEW but does not provide a specific required number, making it unanswerable without additional context.
Step-by-step explanation:
The subject of this question involves the procedures and policies related to law enforcement, specifically regarding Conducted Electrical Weapons (CEWs). A CEW, also known as a Taser, is a type of weapon that law enforcement officers may carry. The query does not provide a specific number of cartridges that must be carried by an officer issued with a CEW. Therefore, without a specified number in the question, it cannot be accurately answered. Nevertheless, law enforcement officers are typically required to carry a certain number of cartridges for their CEWs to ensure they have enough to properly perform their duties, though the exact number may vary by police department policy or jurisdictional law.
