I read it all.
I don’t see a lot of significance in there except..
ISIS did claim credit, and surprisingly they are not in the habit of falsely claiming credit.
People have researched it and there is only one possibly false claim and even that one is debatable.
Still one can see why any militant group would be eager to claim credit for things beyond they really did, to boost their rep and demoralize opponent.
Despite the lack of false claims of credit, I don’t see this as “proof” or even very good evidence.
But it isn’t nothing either.
I humbly admit I know nothing but am open to possibilities.
