Just another example of what this case represents for too many black people in our country:

The argument can be made that the officers were completely within their legal rights throughout this whole thing, but the thing is that they get to dictate the circumstances. They get the power of telling the people to get out of the car, and the people have to choose to comply and 'be lawful' even though doing so makes them fear for their life.
Basically, an officer fears for his life and he is allowed to use lethal force. A civilian fears for his life at the hands of an officer and if he tries to protect himself by calmly remaining inside a vehicle, he'll get cut by flying glass and tazed.
I've been pulled over and reached my hands places that the cop couldn't see plenty of times in my life going for an id or registration. I've never felt like I needed to be afraid of something like this, and I've never had an officer become alarmed at me doing so.
