The problem is that Racism has been proven, time and time again. The reality is that the Law and Order folks explain it away.
We are collecting, releasing, and analyzing data on millions of traffic stops across the United States.

It was discovered that Blacks were more likely to be pulled over in daylight. Oddly enough, once night fell Blacks were no more likely to be pulled over. Whites drove more but were pulled over less. The argument that Blacks were worse drivers or more likely to speed or drive recklessly does not explain the lower rates of being pulled over at night. Are the Blacks more likely to drive within the law at night?
Blacks were more likely to be searched. Yet, Whites were more likely to have contraband in their cars. Somehow this statistical reality did not change the focus of police searches. The Police continued to search Blacks more despite a lower probability of finding contraband.
It goes on and on. So we have demonstrable proof of Racism in the most common police interaction, the traffic stop. How about the actions of the courts? Blacks normally get stiffer sentences than whites when found guilty. Similar criminal histories does not result in similar sentences. So if you eliminate the nonsense, you are left with Racism.
It goes on and on and on. Yet those who are demanding Law and Order never demand all of the laws. They detest the idea of the Constitution actually demanding that people are given equal treatment and equal opportunity.
So yes, there is systemic racism.
No, I disagree with all of that.
For example, they found that nearly all officers had no idea the color of the driver, before making the traffic stop.
When the officer is watching someone through a radar gun, or laser gun, they have no idea who is driving. All they know is, the car is going too fast.
Moreover, one of the reasons traffic stops tend to decline at night, is because officers are usually dealing with other crime at night, and are less likely to make a traffic stop.
Has nothing to do with them being black or white. All traffic stops for all people, are greatly reduced from about 7 PM to 2 AM. At 2 AM traffic stops pick up again, because officers are very aware of when the bars close, and actively look for intoxicated drivers.
Oddly, the researchers themselves are more honest with their data, than the people who use the data to come up with politically motivated conclusions.
From your link:
"For example, driving behavior and time spent on the road likely differ by race or ethnicity. The racial composition of the local population also may not be representative of those who drive through an area, especially when dealing with stops on highways."
"But if minorities also happen to carry contraband at higher rates, these higher search rates may stem from appropriate police work."
"For black drivers, search hit rates are typically in line with those of white drivers, indicating an absence of discrimination."
"In this hypothetical world, consider a fair police officer who only searches drivers with at least a 10% chance of carrying something illegal — regardless of race. In that situation, the white hit rate would be 75% and the black hit rate would be 50%. The officer used the same standard to search each driver, and so did not discriminate, even though the hit rates differ."
"For example, if officers suspect more serious criminal activity when searching black and Hispanic drivers compared to white drivers, then lower search thresholds for these groups may be the result of non-discriminatory factors. Our results are just one step in understanding complex police interactions."
So throughout the research that you yourself posted, over and over and over, the researchers admitted that it is entirely possible that all differences may not be any indication of actual discrimination or racism.
I'll give you a simple one.... real simple example that this research never eluded to.
Attitude.
People with an attitude towards police, are more likely to be searched. Guarantee it.
If you have an entitlement, and all police are racists attitude, an officer is going to be naturally suspicious of that individual, over an individual that says "Yeah, I was speeding. Here's my license."
If the officer says "Put your hands on the steering wheel", and you say "Yes sir" and put your hands on the steering wheel, do you think the officer is more likely, or less likely to be suspicious, than if you yell back "Why should I? Why did you stop me? I have rights!"?
And this is true of all races. If you have some white chick, screaming at the officer, saying "you can't stop me"... guess what that officer is going to do? He's going to stop her, and search her car.
I've seen videos of this. There was one not too long ago, of a older white lady, copping a full on superiority entitlement attitude, and the officer bashed the window, and dragged her out of the car.... and rightly so.
Different groups, tend to have different attitudes towards police.
If only 10% of whites hate police, and 50% of blacks hate police, and then even if the officer pulls over an identical percentage of each group... because of the attitude difference, he is more likely to search one groups cars over another.
That's not racism. That's the natural results of different groups interacting with police differently.
