Just going to go out on a limb here: “Religious texts” stating that Allah is great would not be the sort of texts that the FBI would be allowed to flag for warrantless searches, right? …

That was protected religious expression which is forbidden to be used for investigatory purposes.

But your Gutter Religion, Christians? It’s open season on you.

[It’s not for nothing that the FBI attempted to flag ‘rad-trad Catholics’ for their preference of the Latin Mass. — Ed]
