It might have been Leo Terrell’s finest moment. As a career civil rights attorney, Terrell has spent three decades making arguments in courtrooms. As a Fox News contributor since late January, he’s been making arguments regularly on national television through most of the nascent Biden administration. But the argument Terrell made Tuesday night against regular Fox sparring partner Geraldo Rivera was one every American needed to hear — even, or especially, liberals. The clash came during a segment on “The Faulkner Focus” about the latest leftist boogeyman of “systemic racism” in law enforcement, the ludicrous idea that police officers in the United States are effectively a militarized force deliberately targeting black men for death. The phrase — or its equivalents — is a standard trope of “civil rights leaders” and condescending liberals ranging from MSNBC host Al Sharpton and avariciously histrionic attorney Benjamin Crump to President Joe Biden, and parroted by millions of delusional Democrats on a near-daily basis. But it’s baseless, as Terrell argued on Tuesday — and Rivera couldn’t muster a coherent word to contradict him.
