Ah, so now it's not about unreported terrorist attacks by Muslims.
It's "instances that have occurred where I don't think they've gotten the coverage it deserved."
Presumably anything short of wall-to-wall coverage with scary music of any serious crime by a Muslim in the past 5 years constitutes not "the coverage it deserved".
Still, last week's murders of Muslims in Quebec did get the coverage they deserved: they got used by Angry Spice to Spice-splain Trump's travel ban.
