Your examples of failing regulations, isn't an argument against regulation, but rather a proof that those regulations are as needed now, as when they where made. But they need to be enforced. To do that, you need a willing and able government.

Citizens will disagree, be uninformed, misinformed, and most won't even care. Just look at the last 10 years of protesting: 99%, blacklivesmatter, Charlottesville Rally. They all made anti-movements as vocal and strong as the movement itself. No progress made by vigilant citizens. What is the better justice system.. lynch-mobs acting on feelings and rumors, or trained police and skilled judges acting on the facts, where both parts can tell their side, with laws equal for everyone as guideline. Maybe the system don't work as well as it suppose to. But you won't get better justice by tearing it down. Only solution is cleaning it up.
