So he is lying about arriving at the downstairs apartment around 8:30pm? Where was Knox, Sollecito getting wasted at? They both have a pretty solid alibi, according to the prosecution, from 8:30pm till 11:30pm. Did curatolo testify that Knox and Sollecito where drinking or smoking pot at the court from 9:27pm till 11:30pm? Notice i said Knox and Sollecito because your Super Witness never saw Guede. You keep making this claim that all 3 where together getting wasted but the prosecutions timeline and witnesses has Guede no where near Knox until just after 11:30pm. So where was Rudy between 8:30pm and 11:30pm since we know he wasn't with knox/sollecito.
Plus if they didn't meet up until 11:30, then rudy would have had to done all this after 11:30pm:
Take a crap, drink from the fridge,
Beat up Meredith, sexually assault her, stab her in the neck,
Go fetch towels from the bathroom and wash his hands,
Come back to her while she is still alive and leave the towels with her body, Rummage through her purse and then leave.
