This article in The American Conservative has some excellent analysis of the Hispanic crime rate.
When adjusting for age (because it’s well known that criminals are most likely to be young males), and only looking at state prisons (because the vast majority of the incarcerated are in state prisons, while federal prisons contain a lot of people incarcerated for immigration offenses), outside of the northeast, the Hispanic incarceration rate is actually lower than the white incarceration rate.
The higher Hispanic incarceration rate in the northeast is due to a larger percentage of northeastern Hispanics being black Hispanics (mostly from Puerto Rico and the Dominican Republic), and the same graphs which show Hispanics not being any more criminal-prone than whites show blacks being a lot more criminal-prone.
In Florida, where a disproportionate number of “Hispanics” are Cubans of white Spanish-European descent, the Hispanic incarceration rate is less than half the white rate.
It’s even possible that, when adjusted for IQ (Charles Murray demonstrated in the Bell Curve that low IQ puts people at risk for criminal behavior), non-black Hispanics are less prone to criminal behavior than white Europeans.
The conclusion is that, as long as non-black Hispanics are taught good values and kept away from the bad influence of American blacks, they don’t pose an imminent threat to law and order.
