I assume she will get a settlement, the city (the taxpayer) will pay for it and nothing else changes. There will be even less money for infrastructure repair and people will keep voting for the same people.
That's not a fair assumption in the current political environment.
Those who have lots of money will get fair hearings under the court, but those with less power might not. There's a reason people like Elon Musk write into agreements that they must be settled in particular Texas courts.
I think everything is consistent with the perspective Texas represents toward the united states. It's fine if Texas doesn't implement reforms and fails. (There are 49 other states and may the ones that invent or adopt the best practices survive.)
The point of the arrest was not to win. The point was to inconvenience the whistleblower, cause her grief, and maybe as a bonus make her spend a night or two in jail. Nobody doing this remotely believed that they wouldn't have to settle. They did it to show that if you speak out against them, they'll arrest and inconvenience you. So the next person who gets a thought to speak out might decide not to bother.
Same for the guy in TN who got arrested for posting that anti-conservative meme. Nobody thought they would win, but they want to make everyone else think twice about criticizing a particular political side.
