The government doesn’t benefit by solving the problem but they do benefit by playing to them. This kind of campaign may lead to ‘legal’ police raids on legitimate gun owners and may even lead to shooting those owners. Many people may hate their neighbors and file reports just to harass them. I also expect that there may be many cases where the city renege on their offer to pay out $1000 and this offer will eventually either be rescinded or it will become a crime to falsely report legal gun owners if it gets out of hand. Win-win for more government bureaucracy.
