What's a poor liberal Democratic mayor to do when she wants to get fellow liberals to behave and they won't play ball?
She screwed up by not having a handle on the situation in the first place. If it was just a rogue cop responsible for this, then I might see giving her a pass, but she's the mayor. She was undoubtedly the one who sent the police in and authorized the level of force used.
I have no doubt she's trying to pull her own ass out of the ringer and toss out some sacrificial lamb (probably a police officer) for the injuries, but she'll be lucky to recover from this screw up.
Again, the responsibilities of leadership state that they should be smarter than the masses because it's their job to do so. The city, from the Mayor on down, were stupid. They let themselves be put into a situation of reacting instead of being proactive. It's not like this popped up in just a couple of hours and they were desperate to do something. This thing had been going on for days. More than enough time to think it through.
I bet mayors across the nation are pulling in their managers, heads of first responders and other leaders to plan what they would do in such a situation because, if the movement continues, it is sure to confront other city mayors. They better have a handle on it or they'll be facing public scrutiny for screwing it up.
