It'll probably disabuse you of the idea that its a good way to get things done.
Democracies that arise by nonviolent revolution, do so in part due to the threat of what comes next if the nonviolent revolution is crushed. Because if you make sure placards and petitions don't work, it eventually won't be placards and petitions anymore.

When I've gone to local government meetings, I've generally been one of only a few without gray hair. The vast majority of working-age people seemingly can't be bothered to learn the basics about who's running in a non-presidential election, let alone go argue for the boring but extremely impactful things that would actually help people out.
People need to put down the phones and put in some actual effort on fixing things before even jokingly advocating for something that would almost certainly be a mass casualty event. It's shameful.
Resistance doesn't work very well against highly militarized autocratic regimes.
