Wrong. http://cis.org/ImmigrantCrime
1 - The issue is people sneaking across the border in the dead of night with no background checks or health-screens. No records, no documentation, nothing. YOU don’t know which of them are rapists or the worst human being walking the face of the Earth…the US government DOESN’T know per your own comment. You can’t keep tabs on people if you don’t know who they are or where they’re coming from…they’re ghosts.
2 - Do you leave your home unlocked letting random people come and go as they please using your resources, letting them hang out with your kids because “immigrant populations are more law-abiding”? LOL I’m betting NO. By the way buddy, does that ‘immigrant’ population study focus on legal immigrants? Because again - http://cis.org/ImmigrantCrime
You are starting with inaccurate information. So, the last question you posed is merit-less.
Whites are 63% of the population, but blacks commits AS MUCH MURDER as a population of 63% whites, but blacks are only 13% of the population. That’s not racist, that is a fact. But illegal aliens? I don’t care how many Americans are in prison for murder…those are Americans. We have enough problems to deal with let alone letting millions of people sneaking across the border, using our resources, using our infrastructure on and on and on.
