Gender profiling of those Driving While Male (DWM) and age profiling of those Driving While Young (DWY) is far more systemic biased policy than any allegations about so-called DWB. Men are pulled over much more disproportionately as are those who are young.
But since there’s no political brownie points to be earned by left-wing politicians and media potato heads in pointing out the DWM and DWY realities, they rather try to stir race wars by focusing on race issues to maintain their ownership of the black vote.
