OK let's get back to this now. First off, I need to correct you. When you wrote "Tim knows this but steadfastly refuses to acknowledge it"- that's not true. It really never occurred to me, until you brought it up, that incarceration rates are not tantamount to crime rates, and in fact I have no way of knowing that it isn't. Even if the rate of incarceration doesn't exactly match the crime rate, I'd be pretty surprised if it was way off in terms of percentage of illegal immigrants.
Second, it's not one study I have used to back me up. I have listed several studies, one after another, about illegal immigrants and violent crime, and they all suggest the same conclusion, that by percentage, illegal immigrants commit less violent crime than do native born Americans.
Now let me add two points that you did not address, but others did in their response to me:
1. Several people noted that illegal immigrants are, by definition illegal; therefore they are criminals. First off, the act of entering this country illegally is a misdemeanor, so it's ridiculous to regard them as criminals on the level of serious law breakers, who commit felonies. Second and more importantly, I was discussing violent crime (as was Donald Trump last night
therefore, the act of being illegal in this country is irrelevant to whether or not they commit violent crimes once here.
2. Others pointed out that many of the statistics I have cited combine legal immigrants and illegal immigrants. This is true. Unfortunately we don't have good separate statistics on illegal immigrants
unless they get caught doing something wrong- obviously they're not about to respond to polls or surveys. However, and this goes back to my response to DW's point, we DO know how many illegals are incarcerated for violent crimes, and that gives us some indication of what percentage of them actually commit said crimes. And if that number is consistently lower than native born Americans we can reach some conclusions- conclusions which are the exact opposite of what Donald Trump implied last night.
