From one city with a very diverse police force using data from the police force. That's proof. And even if you say, okay, I will take this data at face value, and I understand that a lot of the protesters are talking about minorities being killed, Fryer says that there is a lot of racial discrimination by the cops and blacks are much more likely to be manhandled, pulled over, arrested, beaten, etc. so using this study to claim blacks are not targeted or abused by the police more than whites is worthless.
