OK - I see where you're coming from: You rob a liquor store, and the police are after you and arrest you. Only you find that they also believe 2 men were in on it with you, and in fact did most of it - you were just an accomplice. You can't believe your good luck, and say, "yeah, I was just going along with them."Yes, why didn't he? Why did he deliberately choose to leave Amanda and RS out of the picture, in the innocent scenario. When they were already placed in the scene by the investigators, according to the innocent scenario, the investigators already did all the work for him.
So why didn't Guede do this?
If the 2 are innocent, he would still have been likely to have used them. If guilty, why not? The only thing I can think of is, he maintains he had a date and did nothing wrong at all.(just like you might say you were only in the liquor store to shop---you had NOTHING to do with it.)
