Ghirga also rejected insinuations that Knox did not get a fair trial in the Perugia court. "The issues in America do not interest me much," Ghirga told ABC News. "I am happy that there is support, and participation, but if you say it was a trial from the Middle Ages, that her rights were violated, then what do you have lawyers for?"
"Amanda's rights were respected during the trial," said Ghirga. Over the course of many hearings "evidence was presented in the course of debate in court. She had a fair trial."
Knox's rights were not respected during the investigation, however, Ghirga said, when Knox was questioned without a lawyer in the early days after the murder, and interrogation that led to her confused statement in which she said she had a vision she was at the house when Kercher was killed.
"During the investigation, her right to have a lawyer present was not respected, and we made that point very strongly in the trial," Ghirga said.
While noting that "we all were influenced by the media" in the course of this case, he ruled out that the media coverage of the case ultimately influenced the jury's decision.
"I rule out the fact that the jury could have been influenced by the media in a negative sense," Ghirga said. "And I can guarantee that at the trial, the rights (of Amanda) were not violated."
Italian observers commenting in the press bristled at what they felt was uninformed judgment of the case by American media and commentators.
"I don't know if Amanda Knox is guilty," wrote reknowned commentator and U.S. observer Beppe Severgnini in an editorial in the Corriere della Sera on Tuesday, "or at least I did not know until Saturday, Dec. 5, when the jury convicted her."
"I am in the habit of respecting verdicts...It is unthinkable that the jurors in Perugia could have decided to convict a girl if they had a reasonable doubt. We accept that. The American media do not," he wrote.
"Television networks, newspapers and internet sites in America are convinced that Amanda is innocent," contined Severgnini. "Why? We don't know. Did they follow all of the hearings in the trial? Did they evaluate the evidence? Did they listen to the witnesses who, what's more, testified in Italian? No, obviously: they just decided, and that's it."
