It wasn't just property damage, and insurance isn't magic.

David Dorn, a black ex-police officer, and 14 other people died due to the unhandled looting.

If they would have sent National Guard in to protect storefronts those deaths would have never happened.

Those peaceful protesters deserve protection from the looters as well btw.

The peaceful protesters explicitely don't want that. You may disagree with them, but don't pretend it is for them.

I do disagree, and it is for their safety, many of them are getting hurt.

I don't care if they want it or not, if they don't, they don't know what's good for them.

The problem here is that the protestors are against what they perceive as excessive use of force. Sending in the national guard would escalate the situation further. One of the reasons these protests persist is that they elicit from the police much of the behavior they detest. The protests are self-fueling.

Letting them do whatever they want is not a valid choice, no matter how they feel.
