I am not hearing “if” in there.
He doesn’t say “if” and his phraseology is awkward.
But the question was... “what will you do to help eliminate inner city kids partaking in crime...”
And he says “... You start with the President of the United States saying to America we cannot build enough prisons to solve this problem and the idea that we’re gonna just keep incarcerating and keep incarcerating - pretty soon we’re not gonna have an African American population - they’re all gonna be in prison, or dead.”
