Some have said it's debunked because the pic has the Presidential seal on the hearse, so it's fake.
Others say the picture isn't really the photo from the scene, and that it's a placeholder/visual representation for some readers.
No real consensus yet, and no hard evidence for or against.
My 2 cents: I wouldn't put it past the DS to pull another GHWB to delay POTUS's big SOTU address using RBG's dead body.
