2:10 pm: Here's a summary of reactions over the fifth witness, Captain Mohamed Abdel Hakeen Mohamed of Egypt's Central Security Forces.
The most serious challenge for the defendants' lawyers so far has come after Judge Refaat decided to hold Mohamed in custody.
Plaintiffs' lawyers and prosecutors told the judge that the captain changed his testimony, and accused him of perjury.
During his testimony, Mohamed denied the use of live ammunition against protesters. But in March, he told prosecutors that Central Security Forces were supplied with live ammunition.
So far, only one witness, General Hussein Saeed Mohamed Moussa, head of communications for Central Security Forces, has testified against any of the accused.
Moussa said Ahmed Ramzy, former assistant minister for the Central Security Forces, ordered the supply of the Central Security Forces with live ammunition.
Nabil Medahat Salim, Ramzy's lawyer, told Al Jazeera that the first witness's testimony doesn't pose a challenge for Ramzy, because the witness didn't realize any orders to supply forces with automatic weapons and only heard it over a handheld radio.
All the witnesses so far are various ranking police officers who belong to the same department in the Central Security Forces.
Meanwhile, one of the lawyers has demanded that General Mohsen al-Fangary, assistant defense minister, be summoned to testify about the killing of protesters.

Like the other prosecution witnesses, he denies the use of live ammunition during the revolution. He only learned about the shooting of protesters from TV, he says.
State TV reports that Judge Refaat asked Mohamed, "What were you assigned to do between 25 and 28 January?"
Mohamed replied, saying that between 25 and 27 January, he was stationed in the Central Security Forces camp. On the 28th, he was sent out with the first brigade.
"What kind of arms did you carry?" Refaat asked.
He said soldiers and officers were armed with sticks, shields, tear gas bombs and pistols loaded with pellets. He denied that Central Security Forces were armed with live ammunition.
The judge said, "Some victims were shot with live ammunition, who you think had shot them?"
He replied saying, "I do not know." He added that Central Security Forces officers are usually prohibited from carrying any machine guns or their personal pistols - which normally are loaded with live bullets - when they are sent out to demonstrations.
