2016 Contender Donald Trump Previously Slammed Mexican Immigrants As “Rapists,” Criminals

Trump: “When Mexico Sends Its People ...They're Bringing Drugs. They're Bringing Crime. They're Rapists.” Republican presidential candidate Donald Trump characterized Mexican immigrants as criminals and “rapists,” saying that “the U.S. has become a dumping ground for everybody else's problems” during his campaign announcement speech on June 16:

TRUMP: The U.S. has become a dumping ground for everybody else's problems.

Thank you. It's true, and these are the best and the finest. When Mexico sends its people, they're not sending their best. They're not sending you. They're not sending you. They're sending people that have lots of problems, and they're bringing those problems with us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people.

But I speak to border guards and they tell us what we're getting. And it only makes common sense. It only makes common sense. They're sending us not the right people. [Time, 6/16/15]

Right-Wing Media: Murder Validates Trump's Characterization Of Mexican Immigrants

Fox's Tantaros: Trump Was “Pounded Down” For Immigration Comments. "Now We Have A Story Like This." On the July 6 edition of Outnumbered, host Andrea Tantaros said of Trump: “The debate last week was anyone who spoke up about illegal immigration or deportation or sealing the border was pounded down by NBC and by stores like Macy's -- we all know who I'm talking about.

American Thinker: San Francisco Murder “Is Validating The Argument Of Donald Trump.” In a July 4 blog post, the conservative American Thinker wrote:

The horrific murder of a pretty young woman by an illegal alien at a prime tourist location in San Francisco is validating the argument of Donald Trump on the influx of violent criminals, and causing at least some local media reflection in arguably the nation's most politically correct city.  [American Thinker, 7/4/15]

The American Spectator: Trump Spoke “Hard, Documented Fact” About Immigrants, “Illustrated By” This Murder. In The American Spectator, former Reagan White House political director Jeffrey Lord claimed that Trump's “mere recitation of hard, documented fact when it comes to illegal immigration and crime” had been “vividly and outrageously illustrated by (yet again) the murder of Kathryn Steinle”:

Yet in the world of Republican presidential candidates there is Donald Trump calling repeated attention to the fact that illegal immigrants are in fact pouring over our southern borders and, exactly as he has said, committing serious crimes. This is a fact -- a well and easily documented fact long before the real Kathryn Steinle lost her life at the hands of an illegal immigrant. And -- yes, let's say it -- that illegal immigrant had his freedom to murder because of liberals who made San Francisco a sanctuary for criminals. And lets [sic] not forget the President of the United States who encouraged illegals to think they could come here illegally in the first place. [The American Spectator, 7/6/15]

But Studies Show Immigrants Are Less Likely To Commit Crime Than Native-Born Americans 

Study: Crime Rates Higher Among Native-Born Americans Than Immigrants. A 2013 study in Criminology and Delinquency found that “first-generation immigrants commit crime at a lower rate than second-generation and native-born, non-Hispanic whites,” as ThinkProgress explained.

Northwestern University: “Essentially No Correlation Between Immigrants And Violent Crime.” Northwestern University professor Jörg L. Spenkuch used nationwide FBI crime statistics and records from every county in the US and found that there is “essentially no correlation between immigrants and violent crime,” according to a 2014 article.

Study: Incarceration Rates For Young Men Lowest Among Immigrants. According to a study by the Immigration Policy Center, a division of the American Immigration Law Foundation, the incarceration rate of men aged 18 to 39 was five times higher for the native-born population than for immigrants:

Among men age 18-39 (who comprise the vast majority of the prison population), the 3.5 percent incarceration rate of the native-born in 2000 was 5 times higher than the 0.7 percent incarceration rate of the foreign-born. [American Immigration Law Foundation, Spring 2007, via Media Matters]
