Germany has an issue with criminal clans from the Middle East, our law enforcement system isn't equipped to deal with them and our laws in general aren't either. The approach is pretty much "try not to engage", because while it's damaging to have "extended families" with hundreds of members where basically everyone of them has a criminal record, the other option is either locking up everybody (terrible idea in Germany) or trying to reason with them and failing (showing the state tried to handle it but failed). Not engaging is just the cheapest option and does the least amount of damage (I'm not suggesting that's necessarily true for the situation in the US, I don't know it well enough).
If the Leviathan shows its teeth and the problem doesn't go away, it has to bite. If it doesn't, everybody will see that the teeth aren't that sharp any more, and that will encourage more challengers.
> The state's power is not just fear alone, it's legitimacy.
For the people that don't require laws and punishment to behave morally, yes. For those that do, they obviously don't care about legitimacy or that looting (or any crime) is wrong, otherwise they wouldn't commit it. It's only those people that any society needs to worry about, and it's only those people that the state needs to convince that it is stronger than them.
But that's effectively what doing nothing does. The state has teeth (the police) and it doesn't bite.
That's a completely unambiguous signal to both criminals and law-abiding citizens. And the results of this policy anywhere in the world is the problems have just grown in size and gotten worse.

Remember when these "extended families" were an order of magnitude smaller and we applied the same policy of non-intervention? And look what that got us!
When are we finally going to apply the only acceptable course of action?
There is a big disconnect between the crime statistics in Germany, that show low crime levels by international standards and recent reductions in crime levels, and what the German public believe about the prevalence of crime in Germany due to alarmist tabloid reporting.
Cf. e.g., https://www.dw.com/en/crime-in-germany-drops-10-percent-in-2...
Kind of, but not really. If you send the police to confront the looters, you are showing your teeth, you're saying "this will stop right here and right now, or else". You have to have a plan for the "or else" part.
If you don't send the police, you're not saying anything. Everybody is aware that the police exists, but unless you assert your power, there is no challenge.
This is obviously not a possible long-term strategy, because not having any power and never asserting the power you have are functionally the same. I don't think that anybody assumes the rioting will be a long-term problem though, so that may not be an issue.

We won't. We're doing harm-reduction, both on a society level and, for politicians, on an individual level (and for management in large companies). Kick the can down the road. Attacking the big problems before they become unavoidable isn't something our systems are set up to do, not causing disturbances is incentivized, be that in law enforcement, dealing with dead industries surviving only on subsidies, education, pollution and emissions, health care, public infrastructure etc pp. "Spending $5m on that bridge now will save us lots of money in the future" isn't what the public sees - it's "they want to waste $5m on a perfectly fine bridge".
