Savannah policemen find out they have the wrong man and then charge the man they assaulted with "Obstruction".
This incident is the product of the mindset which says, "I am a uniformed Tool of the State! I cannot be wrong! All mortals must bow before me and submit!"
Remember, these policemen believe they did nothing wrong. They believe they did the right thing. They are proud of themselves. All of their co-workers will back them up. They will never be corrected from within their own chain of command.
I can hear the refrain now, "Why didn't he just submit...?"
Is that how Free Men behave? Our ancestors would be ashamed of us.
