I didn't say a single witness watched them the entire time, so no I didn't say anything that was factually incorrect. My understanding is that witnesses saw them get out of the vehicle at the strip mall but didn't see them dispose of a gun there. If they didn't do it there, where did they do it?
Do you think it's plausible that the kids had a gun and dumped it somewhere within a few hundred feet of the scene of the crime when they could have just as easily kept driving and dumped it somewhere on the way to a hospital?
That's not plausible at all. I don't think you're on the fence, I think you really, really want to believe Dunn. All he had to do was say these kids had a gun and you've abandoned all logic to believe him.
He may have thought that he saw a gun, but he didn't.
