The tag we use for this is MSM Backlash Libel.
(Steve Sailer prefers the term "Frontlash."
)When a Muslim or other immigrant commits an atrocity of some kind, the MSM worries not that more Muslims, etc. will commit more atrocities, but that native-born Americans, Britons, or Frenchmen be unkind in some way to the mass murderers' fellow countrymen
The speed of modern media means that they can start not just while the dead lie unburied, but before some of them have actually finished dying.
Here's the MSM backlash libel about the Bastille Day atrocity in France as reported in the Washington Times:
In an interview on Fox News, presumptive Republican presidential nominee Donald Trump said the Nice attacks vindicated his tough stand on immigration and Islamism, even though the killers hadn’t been identified.“We’re trying to be so politically correct and we’re making such big mistakes,” he said. “If it’s radical Islamic terrorism, [President Obama] ought to say it.”He said that if he were president, “I would not allow people to come in from terrorist nations.”In a statement released shortly after Mr. Trump’s interview, Mr. Obama called the attack “terrorism.”“On behalf of the American people, I condemn in the strongest terms what appears to be a horrific terrorist attack in Nice, France … we stand in solidarity and partnership with France, our oldest ally, as they respond to and recover from this attack,” he said.Fernando Freitas, a Paris waiter who immigrated to France from Portugal in 2008, said he’s somewhat worried this attack will cause backlash against immigrants in general, even though it wasn’t known right away who the perpetrators were.“Maybe there is some chance it was not. But even if we don’t know, I’m thinking it’s the Islamic State,” said Mr. Freitas, 49.Mr. Kerdoni, a Muslim who came to France 15 years ago from Morocco and has two children raised in France, told The Times that he already fears what politicians such as Marine Le Pen of the National Front will do.“Yes. Every time this … It’s a good opportunity for Marine Le Pen … 90 percent of the people are not against any Muslims here, but the right wing will profit from this even if the people who did this are not Muslim,” he said.More than 70 killed as truck crashes into Bastille Day crowd in Nice, FranceBy Guy Taylor and Victor Morton - The Washington Times - Updated: 8:40 p.m. on Thursday, July 14, 2016
That was published 51 minutes ago as I write—it's possible that the emergency vehicles pictured above haven't even delivered all the wounded and dying to hospitals. Here's video of the attack, so you can see what the backlash, if any would be about:
