Of the 7,175 reported hate crimes reported nationwide in 2017, only 23 were found to be false, according to police and FBI data collected and analyzed by Brian Levin, a national expert in hate crimes and director of University of California, San Bernardino's Center for the Study of Hate and Extremism. In 2016, 16 of the 6,121 reported hate crimes turned out to be hoaxes, according to Levin, who’s also a former New York City police officer.
That means, for both 2016 and 2017, only about .03 percent of reported hate crimes turned out to be fake.
Levin’s numbers from 2018 still aren’t finalized, but he’s estimated that 7,750 hate crimes were reported nationwide last year, and so far, just seven have turned out to be hoaxes.
