Yes, it’s true that Clinton in 1996 referred to certain young black men as “superpredators,” a characterization she has since said that she regrets (though not until she was prodded by a Black Lives Matter activist).
But perhaps Trump forgot that time when he demanded the execution of five teenagers (four black, one Hispanic) who were wrongly convicted in a rape case in 1989 in New York City. He went as far as to take out $85,000 in newspaper ad space advocating for reinstating the death penalty, thus fanning the racially charged fears of the city.
