Why not? It gets across his frustration with his local newscasters quite colourfully, I think. I doubt he expected anyone to say, "Omigawd, only a monster would seriously want innocent people to die!" when it's perfectly obvious he's not being serious.
And I can empathize! I'd love to have a professional, well-spoken anchor like the one in the OP. Her speech brought me to tears.
My local crew, though? The elderly fellow who slurred all his words, tipped to the side, and occasionally lost his place when reading has finally retired. We used to wonder if he kept a wet bar under the desk! Now the folks replacing him, who used to be okay, are stumbling over their lines and mixing up their words and looking flushed and spacey. Which pretty much confirms that he passed on the key to his private bar when he left!
There's one lady, who has been regulated to late nights, who keeps getting fatter and fatter and fatter. She's easily three times the size of the lady in the OP. And then there's the fashion expert, who couldn't get any more skeletal and horrifying if she tried. The skin on her face looks like it's been pulled so far back, there's nothing but bone under there. And her mannerisms and voice are deeply irritating. Honestly, I prefer watching the fat lady read.
Oh... and then there was the time the anchor looked at the field of daffodils and said, "The tulips are certainly blooming early this spring. Just look at all those beautiful tulips!" Cut to commercial, and when we come back, he's saying, "Don't write! Don't text! Don't e-mail! I KNOW what a tulip is!"
And if after the show he'd turned to someone off camera said, "Whoever wrote my script needs to die," I doubt anyone would accuse him of making death threats.
