They're hoping for an easy settlement; they won't get it. They've got frig all on this; it was a justified, clean, and restrained shoot (one shot only) that only came after the crowd was crossing a final line in the sand, beyond which the police would be unable to protect the people they were safeguarding.

And it worked. I'm just amazed there weren't several more people shot that day, given the totality of all the various assaults on police that we've seen video of.
