One of the complaints by the ACLU was that 39% of the false matches of congressmen to mugshots were people of color, even though only 20% of congressmen are PoCs. This is a subtle way of saying that the mugshot dataset is probably not representative of the US population as a whole because it overrepresents PoCs. Although, it's important to note that machine learning algorithms generally have a more difficult time with darker skin because of lower contrast (see scandals on Google identifying black people as gorillas and cameras not auto-focusing on black people). It is a legitimate concern that black people may be misidentified more often with any machine learning algorithm.
