Read it already. 
Since neither of us were there, unless maybe you were? (I know I was not), difficult to ascertain  how much lack of control and force was used by the fire chief. 

Comparing a work place assault (even low level) between 2 adult workers is very different than an at home parent-teenager situation where you are responsible for your teen even if they don't think you are. 

I can only tell you, as other workers did in Seattle, that we had a boss who would assault people physically and verbally and very little was done about it due the culture of fear that existed at that workplace. The constant work related stress we were all under allowed the boss to continue this behavior for a very long time.
