Limp, then no limp, on the roof
Open
Hull: 11:50 figure walked with a limp not seen that morning. Affidavit reporting: limp gone once on the roof. Press: limp consistent with a rifle in the pants.
If the same person, the limp should have a physical cause (weapon, injury, gait). If two people, the clothes-change plus limp is the splice. Native video, not press paraphrase, is the way to test it.
