The facts are clear: numerous studies have shown that immigrants not only commit less crime than native-born Americans, but higher levels of immigration actually equal safer neighborhoods:

Research has shown virtually no support for the enduring assumption that increases in immigration are associated with increases in crime. Immigration-crime research over the past 20 years has widely corroborated the conclusions of a number of early 20th-century presidential commisions that found no backing for the immigration-crime connection. Although there are always individual exceptions, the literature demonstrates that immigrants commit fewer crimes, on average, than native-born Americans. Also, large cities with substantial immigrant populations have lower crime rates, on average, than those with minimal immigrant populations.

As for Trump’s claim that the undocumented immigrant population is really 30 million, Politifact rated that one “Pants of Fire” last year:

Researchers at all of the organizations told us Trump’s statement is wildly inaccurate. There is "absolutely zero possibility" for the number to be just 3 million or as many as 30 million," according to Robert Warren of the Center for Migration Studies, a nonpartisan immigration policy think tank. "There is strong evidence that the number is 11 million, with a plausible margin of error of plus or minus 1 million," he said. Jeffrey Passel, a demographer at the Pew Research Center, called both of Trump’s numbers "virtually impossible".

Yet another reminder that none of this is normal when a government officials grabs attention for telling the truth. But don’t give any credit to Homan, though. During that same press briefing, here was his message to immigrant moms and dads getting torn from their families:
