To the Editor:

“The Undoing of Justice Reform” (editorial, Feb. 18) claims that I misread my data on incarcerations in Arizona. If it had linked to my research, readers would see that the data show that legal and illegal immigrants as a whole have a much larger share of the Arizona prison population than they do of the state population. If illegal immigrants constituted only a small part of that, then legal immigrants’ share of incarcerations would be twice their share of the overall population.

These are reliable classifications based on pre-sentencing reports.
