"They didn't know beforehand"

Exactly! Which is why you missed my point! Why was he pulled over in the first place? What was he doing that the cops thought was wrong? What was his attitude with the cops after he was pulled over? Unfortunately we have only the original poster's words for all this. From experience, I have found that there are always 2 sides to every story, but that it is somewhere in the middle that you will find the truth.

As for being "racist", or a "cop defender", it was the original poster who used the word "racist" in the tags for his post. And secondly, suggesting that there may be more to a story than we know, does not in any way equate to being a cop defender...it is simply a quest for more information.
