Reeferme is more worried about illegals, even though they commit less crime.

"Our analysis reveals two broad conclusions about the criminality of undocumented immigrants. First, undocumented immigrants have substantially lower rates of crime compared to both native US citizens and legal immigrants. Second, over the 7 y period from 2012 to 2018, the proportion of arrests involving undocumented immigrants in Texas was relatively stable or decreasing.

Taken together, these results have important theoretical and policy implications. Regarding public policy, these findings clearly run counter to some of the basic assumptions behind strict immigration enforcement strategies. Debates about undocumented immigration will no doubt continue, but they should do so informed by the available evidence. The results presented here significantly undermine the claims that undocumented immigrants pose a unique criminal risk. In fact, our results suggest that undocumented immigrants pose substantially less criminal risk than native US citizens." https://www.pnas.org/doi/full/10.1073/pnas.2014704117#sec-3
