Sure. So what is the innocent explanation for what happened (in particular the fresh tape over the back of the unit) that doesn't contradict any kind of visible evidence, and doesn't require some kind of moon-logic like Hasan being unaware that his shock collar has prongs and the remote has buttons on it that shock the dog? What would be the reason for him having her wear the collar regularly without wanting to shock her with it, and then lying about what kind of collar it is?

I mean you've had a chance to see Hasan's explanation. You don't have to speculate wildly about what might have happened or claim that it might be some totally new and different explanation you're totally unaware of (or... you kind of do actually, if you want to try to defend him, since his attempt to explain very notably didn't clarify key information like what model of collar he's claiming it was or what features the remote has...)
