This idea that Curatolo said that AK and RS were in the basketball court for 2 hours is total nonsense. There's nothing to do, it is bare, it is frigging cold in November. There is no-one who would stay there for two hours and that's not what Curatolo said in testimony. This is a ridiculous assertion and it's not terribly credible you're all sitting around saying that's what was said in the trial. It wasn't. Fight the case, not the made up stuff that makes you feel better.
Kokomani was discounted as unreliable so I don't believe anything he said. The court found the other three witnesses credible. You're making an argument from your conviction - there's no evidence to support you so no, I don't have any concern because no-one shows they have lied. The fact that you need Stefanoni, Kokomani, Curatolo,Quintavalle, Filomena, the Postal Police attending the same room and an absolute host of police personnel and forensic staff, ALL to be lying, really ought to give you a clue as to how unlikely your arguments really are.
