Didn't see it, sorry.
It's been my experience that folks who don't root for and support the local police are probably criminals. If your not a criminal, let me help you with the logic.
As a witness to whatever traffic stop you would have to compare what you saw from a distance to what was actually going on with the traffic stop.
Of the two of you, who do you think had a better idea about how the situation should have been handled? You with no information or the officer with all the information?
I want you to support your local police instead of second guessing their judgment from a distance!
Join the winning team. The team that says,"that guy must have done something pretty bad".
I think we can all go to bed tonight knowing that nobody ever gets thrown to the ground and handcuffed for doing nothing. That cop knew something you didn't.
