The most effective additional 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 would strengthen the argument against the ordinance by suggesting that the noise issue is not widespread, but rather localized to a few individuals. This could support the opponents' claim that the ordinance may be an overreach and not necessary for the entire community. It would address concerns about rights and enforcement by implying that targeting a small number of noisy residents might be more effective than implementing a broad noise ordinance that affects everyone.
