Fox News may have a rich history of mangling even the most self-evident of truths but even by their standards, "expert" terrorism commentator Steve Emerson turned the nonsense up to eleven when he told viewers:
"In Britain there are actual cities like Birmingham that are totally Muslim, where non-Muslims simply don't go in and parts of London there are religious Muslim police actually beat and actually wound seriously anyone who doesn't dress according to religious Muslim attire."
Fox News perhaps neither knew nor cared if any of this nonsense was true - of course it isn't - but the broadcaster was quickly criticised for giving such idiotic comments airtime.
Now Emerson has issued an apology, stating:
"I have clearly made a terrible error for which I am deeply sorry. And I am issuing an apology and correction on my website immediately for having made this comment about the beautiful city of Birmingham."
Obviously Birmingham is beautiful. Of that there can be no doubt. But based on his earlier comments it seems unlikely Emerson has ever been there, or even seen many pictures. So it's unclear how he knows how beautiful it is.
Did Emerson just assume nobody would check his ridiculous claims? Was he relying on nobody watching having ever been to Birmingham, or knowing anybody there? Or London for that matter?
In his statement there is little by way of explanation:
"I do not intend to justify or mitigate my mistake by stating that I had relied on other sources because I should have been much more careful. I am not going to make any excuses. I made an inexcusable error."
As did Fox News in broadcasting his claims. That lack of editorial judgement saw them become the subject of the hugely popular #FoxNewsFacts trend on Twitter:
