The trial of former Interior Minister Habib al-Adly has been adjourned until Sunday, Egypt's state TV said on Saturday.
Adly's defense lawyers continued to deny charges that he gave orders to kill protesters.
Mohamed al-Guindy, one of two lawyers defending Adly, said former US President George W. Bush committed several crimes against his people and killed American soldiers in the invasion of Iraq but the US has refused to put him on trial, while Mubarak, who claims he did not order the shooting of protesters, is being tried.
"If the police had shot one single bullet at the protesters, we would have had a bloodbath because a bullet shot from an assault rifle injures at least three people when there are large crowds," Guindy said.
Only 17 protesters were killed in Tahrir Square, Adly’s defense claimed.
Guindy also said that Adly Fayed, former head of the Public Security Authority, has said that at a meeting in which he was present Adly did not order the killing of protesters.
On 28 January 2011 the police ensured the safety of Mohamed ElBaradei and opposition journalist Ibrahim Eissa, who were present amid the protesters, he said.
Scores of protesters were killed in Egypt on 28 January, dubbed the "Friday of Anger."
Guindy requested that ElBaradei be summoned to court, adding that he met with police leaders at Istiqama Mosque following the Friday prayers on the same day.
“If security forces wanted to kill them both, they would have done so, but they were protecting the protesters, citizens and public buildings and facilities,” Guindy argued.
