Perhaps the cruelest misconception regarding immigrants is that they bring crime and violence to U.S. communities — the source of Mr. Trump's hateful characterization of Mexicans as "people that have lots of problems... They're bringing drugs. They're bringing crime. They're rapists." In fact, immigrants are significantly less likely to commit crimes than their native-born counterparts, according to the ACLU, which cited a 2000 Justice Department report showing that crime rates in immigrant neighborhoods remain low "even when faced with adverse social conditions such as low income and low levels of education." A 1990 National Bureau of Economic Research study found that newly arrived immigrants, in particular, are almost never involved in serious criminal acts.
