Among other things I imagine he'd point out that this is only a problem if you normalize police not doing their job. Things like this are only a problem when politicians decide they'll be more popular if they treat enforcing the laws of the land as a PR tactic instead of an obligation. The only reason rioters anywhere manage to do as much damage as they have is because every time there's a new BLM or Proud Boys rally every politician decides they'll look better if they yank the leash instead of letting the police enforce local laws.
