What I've seen the PGP claim is that Guede had no convictions for burglary which is, of course, playing word games.
Not only was Guede caught with the stolen goods from the law office, but he had also stolen a knife from the school kitchen and had it in his backpack. That alone proves he was a thief.
It's all a matter of perspective...
During the search of his backpack at the nursery school police not only found the knife from the school, the laptop and cell phone from Paolo Brocchi's office, but they also found a gold watch similar to the one stolen from Guede's neighbor. And not to be forgotten is that he broke into Christian Tramontano's home, witnessed by both Christian and his girlfriend, and when confronted by Christian, Guede pulled a pocket knife on him.
But he had no convictions so it's only fair he be considered an upstanding young man.
Amanda, otoh, was an excellent student. She worked three jobs so she could pay her own way to Perugia. She held down a job in Perugia while still attending college. She had plenty of money in the bank and was recently dating someone from a well to do family.
But Amanda was issued a citation for a loud party so it's only fair she be considered an evil bitch.
Speaking of double standards...
Christian Tramontano and his girlfriend Monika both witness Guede breaking into their place, with Guede pulling a knife on Christian. That very evening Christian sees Guede at the Domus club and mentions it to several people. Two months later, after seeing Guede's picture in the news as a suspect in the murder, Christian goes to the police and reports Guede breaking into his place. His testimony is dismissed. Compare this to Quintavalle, who doesn't report anything to the police until a year after the murder and only on the behest of a reporter. He tells police his epiphany is the result of a picture of Amanda in the news. This testimony is considered indisputable. Now THAT'S what I call a double standard.
