A television station in Baltimore edited video of protesters calling for the jailing of “killer cops” to make it sound like they were chanting “kill a cop.” I find it horrifying that anyone this side of the white supremacist movement would do something so irresponsible at a time when relations between the police and communities of color are already fraught.

David Zurawik of the Baltimore Sun reports that WBFF, a Sinclair-owned Fox affiliate, has called the incident “an error” and posted an apology on its website (which I can’t find on  the station’s home page or its news page this morning). Some error. In fact, the protesters were chanting, “We won’t stop. We can’t stop ’til killer cops are in cell blocks.” The footage was recorded at a protest in Washington on Sunday and was carried by C-SPAN.

If this really was an error, it’s a matter of someone making some pretty ugly assumptions about the protesters. The fact that the line “are in cell blocks” was edited out raises serious questions about whether this was truly an error. Mediaite has posted the original WBFF video. You should take a look.

Is this the media fail of the year? I think so. Bad as Rolling Stone’s false story about a sexual assault at UVA was, WBFF’s ignorant stunt could incite violence. Broadcast stations such as WBFF are licensed and regulated by the FCC. I am not a fan of letting the government poke into matters involving the First Amendment. But in this case I’d say a hearing is in order. We need to know how this happened.
