President Andrew Jackson famously shrugged off the US Supreme Court decision in Worcester v. Georgia by (probably not) saying "John Marshall has made his decision; now let him enforce it!". Like you said, "Laws are worth zero if the law enforcers ignore them with impunity". This is why we need a system to police the police. At some point, we as a society need to commit to forcing those who swear to uphold the laws to also live by them.
Hopefully this results in successful civil lawsuits against these individuals on the basis that qualified immunity does not extend to these individuals because they didn't follow ID laws.
It might not be the justice people want, but taking away people's money is the most effective means of instituting change in the USA. It's entirely the reason that company's try to eliminate our right to sue them.
Laws are worth zero if the law enforcers ignore them with impunity - a lesson familiar from Caribbean and African banana republics.
