I want to give a cheer to the mom who grabbed her kid. She was not happy he was part of the crowd. Of course, some will say it's child abuse (she slapped him). I'm giving her a pass.
There are some other awesome residents. Ones who on their own stood between the ones rioting and the police. One guy was a Vietnam vet (I think his name is Valentine). Some other stand up men trying to diffuse this situation.
The Gray family deserves answers. How they broke his back is beyond me.
I get the frustration. Sadly, burning down what little resources you already have only hurts yourself and the neighborhood. I'm glad these men I mentioned earlier at least tried to show those doing the rioting that there are other ways to protest.
What differentiates an average host and a great host is anticipating unexpressed needs and wants of their guests. Just because the want/need is not expressed, doesn't mean it wouldn't be appreciated.
