Just watched the dashcam footage from this mess, which happened about 1 1/2 hours from where I am right now.
The cop was a complete dick. Yea, she was annoyed and she had a right to be. The video is below. The first car this asshat pulls over, he seems like a normal, nice cop. The pullover with Bland really starts about 1:40 when you see that he pulls her over for not signaling a lane change...when all she's trying to do is get out of the his way.
What I find interesting is that she's an activist for Black Lives Matter, a group committed to exposing and ending this exact type of behavior among law enforcement. Now she's found dead by hanging in her cell. As of yet (and this will likely change, I'm sure), the jail video doesn't show any evidence of movement within 90 minutes of her death. But there is, apparently, some missing 6 minutes of footage. If she did commit suicide, could that be motivated by her being something of a martyr for the cause?
Either way, there sure seem to be a lot of these kinds of things and I'm not saying all cops are bad. My take is that there is a certain percentage of all society which you can write off as being assholes. The same goes for cops, just seems like that percentage is a just a little bit higher for cops.
