That’s not how % of arrests work. If I have 30,000 convicts and 50% of them are Martians, it doesn’t matter if the population of Martians in my state is 50,000 or 8,000,000. They’re still 50% of the convicts.
Similarly, the number of Martians in my state doesn’t affect how many crimes are reported. If there are 100,000 crimes, there are 100,000 crimes. Literally the only impact of the Martian estimate will be how it impacts the total state population estimate. So if Martians are 10% of the population of 10,000,000 vs 20% it would change the crime rate from say 1/400 to 1/440. This is not some mind blowing difference.
The aggregate per capita crime rate is a poor way to measure immigration anyway. The biggest problem still remains the huge consumption of healthcare and education, as well as wage stagnation. They mostly commit crimes against each other. While I’m not crazy about the rampant identity theft and drugs pouring over the border, that’s probably #5 or #6 on my list.
Their likelihood of reporting crime is similar.
And we’ve already gone over the lack of distinction between Mexican “Hispanic” and Cuban/Puerto Rican/Dominican, etc “Hispanic” in most of the data/studies. They’re extremely different. We don’t have many Cuban and Argentinean drug cartels.
A plurality of our legal immigrants should probably be “Hispanic”. But they should be ranging from the entire Latin American region, and not one single country.
