"Donald Trump wants you to think that America is a scary, scary place. In his speech accepting the Republican Party’s presidential nomination, Trump claims that “decades of progress made in bringing down crime are now being reversed by this Administration’s rollback of criminal enforcement.” He unleashes a blizzard of cherry-picked statistics all directed at one purpose — convincing you that crime has run amok and that he is the only thing that can save you. Don’t believe him. The reality is that crime isn’t just on a downward trend, but it has been for a very long time."
