Well, going back to what I said before, I think you were holding certain assumptions to be true that are currently not supported one way or the other, and you were getting called out for that. Two of ones I noticed is that you insisted several times that disguise was involved, and that Amanda's bodyguard was effective and certain to be a major obstacle for Amanda's killer. That's why in the story version I came up with on the spot above, I purposefully presented a viable option where disguise was not necessary and the bodyguard was easily dealt with.
