Yep.
That's where we are, gang. Watch what you say or you'll be destroyed.
Unacceptable opinions will bring consequences.

Yes, if you say something that makes people question your ability to do your job, you will be fired if your employer hears about it.
I worked with a lady who posted her resume on Craig's list, where she said something about the company that was kind of benign. (That the company had been bought out and she didn't feel comfortable.) she was fired for it.
This principal is lucky that he has civil service protections (he's been reassigned), but frankly, if I were the parent of a 14 year old black girl and heard that her principal thought it was okay for the police to brutalize black children (something even the police themselves admit was wrong), I'd have serious questions about the suitability of that person to watch over my child.
