1. So therefore, let’s keep our village police department. Those guys are always there when you need them, and just seeing them around makes you feel safer. Sure, the department costs money, but it’s totally worth it to have peace of mind.

2. In conclusion, our village should keep the police department intact. Our local police are there at a moment’s notice when anyone is in trouble. Being able to see local officers on the job gives residents a feeling of security. The department may cost a lot, but its benefit to our citizens is priceless.

(It restates or summarizes the central idea or claim. It briefly explains how the reasons connect to the claim. It pulls the ideas together with a powerful final sentence.)

Choice 2 is the more formal conclusion because it restates or summarizes the central idea or claim ("our village should keep the police department intact"), briefly explains how the reasons connect to the claim ("Our local police are there at a moment’s notice when anyone is in trouble" and "Being able to see local officers on the job gives residents a feeling of security"), and pulls the ideas together with a powerful final sentence ("The department may cost a lot, but its benefit to our citizens is priceless"). This formal structure helps to provide a clear and concise summary of the argument.
