I've been to a lot of village council meetings. Village of ~2,000 people, I've attended biweekly meetings for ~6 years.
Most (By hours spent) of the debate and dissent came from two lunatics, who, having nothing better to do, would show up to every single one of them. The year after I stopped going, police had to be involved twice.
Occasionally, there would be an interesting conversation, for questions dealing with a lot of money, and non-obvious trade-offs, that were discussed by adults. Most of the time, though, the matters were routine and uncontroversial - or, if they weren't, the councilmembers' minds were made up long before the meeting started.
Nowadays, I hear that they've cut speaking time for members of the public, and restricted their speaking privileges to asking questions. As anyone working at Google or Facebook knows, though, statements disguised as a question are still quite common.
