And Snopes is hardly a reliable source for drawing conclusions that logically follow from the facts.
The claim that " …Trump’s linking of Islamist terrorism to a 13 percent rise in recorded crime “in the U.K.” (or in England and Wales, for that matter) is grossly misleading…" could only be “grossly misleading” if it is proved that very little or none of that rise in recorded crime is linked to Islamist terrorism.
What Snopes has not done is actually show that it isn’t so linked, so the very best they could claim is that Trump’s claim is only POSSIBLY "grossly misleading."
Trust Snopes to be unreliable with their conclusions.
In addition, Trump doesn’t appear to claim “most or all” of that rise is linked to Islamist terrorism. He simply uses the words “amidst the rise of Islamist terrorism,” which doesn’t actually propose a necessary link, just suggests that the rise of one has accompanied or occurred at the same time as the rise of the other.
Trump’s actual tweet:
Just out report: “United Kingdom crime rises 13% annually amid spread of Radical Islamic terror.” Not good, we must keep America safe!
Crucial point: “amid spread of” entails no causal connection but merely that one thing (increased crime) is happening in the midst of something else (Islamic terrorism or unrestricted immigration – which Trump DOESN’T bring up) also occurring. It may mean “because of,” it could also mean “in response to,” or even merely “coincidentally.” Trump’s words alone do not signify any one of those, in particular.
Snopes is in error by presuming that by “amid spread of” Trump meant “caused by.” If Snopes wants to hold itself up as the bastion of truth, they need to up their inferential skills just a wee bit.
