The most effective detail to add to paragraph 3 would be:
“It appears that just a few residents have been causing most of the noise at night.”
This detail directly supports the opponents' concern about the rights of individuals to make noise while highlighting that the issue may not be widespread among the entire community. It essentially provides a counterpoint that could lead to a more focused discussion on the necessity and fairness of the ordinance, aligning with the overall debate on rights and community needs.
