The article posted to HN in this relevant section for the start of this thread (the part about more/less black people in the data sets) quotes/paraphrases a Scientific American piece (where I got the quote with "innocent" in it from my comment), which itself is based on a paper in Government Information Quarterly.
The paper is what the article here links to when they say that facial recognition leads to disproportionate arrests of black people, the part you're mentioning now. That's a separate finding of the paper from the statements about possible reasons "why" that are based on the training and search sets.
The main thrust of the paper is actually those numbers: they find that black-white arrest disparity is higher in jurisdictions that use facial recognition.
"FRT deployment exerts opposite effects on the underlying race-specific arrest rates – a pattern observed across all arrest outcomes. LEAs using FRT had 55% (B = 1.55) significantly higher Black arrest rates and 22% lower White arrest rates (B = 0.78) than those not implementing this technology."
They do some stuff I'm not really qualified to opine on to try to control for the fact that obviously facial recognition adoption is also correlated to department size, budget, crime rate and things like that. Of course the usual caveats still apply, particularly that they're not claiming or attempting to show causation.
