Incorrect. The "cross-race effect" has been extremely well-researched in literally hundreds of scientific studies and has been shown to be present across all races/ethnic groups [[it's not limited to white people, this is true of everyone). Similar effects have also been shown in the literature for age and gender, i.e. we're better at distinguishing between people who are similar in age than we are as opposed to people who are much much older or younger.

So from a scientific perspective, it actually makes sense to have black officers handle facial recognition for black subjects [[as they are less likely to make a mistake than white officers, on average). Where Tlaib is wrong is that black officers would do a better job distinguishing between non-black subjects, as the cross-race effect also applies to African-Americans.
The best solution would be to have a diverse team of analysts, but probably one that is weighted more heavily towards African-Americans given the racial demographic makeup of the city.
