Peter Kirsanow, JD, attorney and member of the US Commission on Civil Rights, in an Oct. 1, 2015 article, "Americans Are Right to Worry about Illegal Aliens and Crime," available at the National Review website, stated:

“[I]n three of the five states above [Arizona, California, Florida, New York, and Texas], incarceration rates for murder and manslaughter were far higher for illegal aliens than for legal residents. Incarceration rates for murder are an imperfect proxy for rates of murders committed (illegal aliens may be more likely to be apprehended, have less competent counsel, etc.), but it’s difficult to contend that illegal aliens are more law-abiding than legal residents — at least when it comes to major crimes. And it’s even more difficult to contend that Americans’ concern about crimes committed by illegal aliens is overblown.

Regardless, comparative crime rates are less important than the absolute number of crimes committed by illegal aliens. Look at California, where approximately 2,430 illegal aliens are in prison just for homicide-related offenses. Even if one assumes that each illegal alien so imprisoned was responsible for just one homicide-related offense, that amounts to about a couple thousand major crimes that, arguably, wouldn’t have occurred but for the actors’ unlawful presence in the United States. That translates to thousands of American citizens (and others) across the country slaughtered by individuals who shouldn’t have been here in the first place.”
