You are all missing the point on the ladder scene.
The camera man is concerned that it might be blood.
He asks if it is.
Then, in a scene edited out of the versions Carol supplied, the camera team investigate, laugh, and say it is paint.
If they had been shocked and said it was blood, Carol and co. would hail that as proof.
Instead she says that they can not tell the difference between paint and blood, because she knows it is blood.

Carol, your murder video shows a weapon that caused NONE of the deaths. You and Lox must accept it is a lie.

Lox, why do you think the boat video is fake?
