The teams of forensic police and four separate judges do not support your What If...? scenario.
It was a transitory student accommodation with no reason to be of any great interest to professional thieves, other than electronic equipment, which, tellingly, was left untouched, as was Filomena's gold jewellery. If Rudy's MO was stealing laptops, then whoever simulated this one, did not copy Rudy well.
Bits of paper scattered about to give the appearance of ransacking were found ON TOP of the duvet covering Mez, one in Filomena's room, had Amanda's footprint on it, glass from the window was ON TOP of the strewn about clothes and most incriminating of all, a footprint encased in blood leading INTO Filomena's room, contained the MIXED DNA of Mez and Amanda (no DNA at all of Rudy in the burglary room). Amanda must have entered that room AFTER Mez' assault. In addition, a shard of glass from Filomena's window was found on Mez' floor. Therefore, Amanda was LYING when she claims she had no idea Filomena's room was in turmoil the next morning, claiming the door was shut, yet Raff said it was "wide open". WHY LIE ABOUT IT???
No doubt someone could climb up to the second floor window, should they be greatly motivated to, as was the professional pro -Knox climber. However, it doesn't logically follow, they did.
