DEBORAH AMOS: Hisham Kassim, a 20-year veteran of Egypt's political opposition, says he never imagined this happening - Mubarak under house arrest with a prosecutor demanding answers.
HISHAM KASSIM: Unless Mubarak can really establish that he is physically incapable of coming to Cairo and facing the prosecutor, they will bring him. Okay?
AMOS: And the minister of justice issued a public warning to Mubarak's son Gamal, says Kassim.
KASSIM: If Gamal fails to show up on the summons that has been made for him, that constitutes a second crime.
AMOS: So you think this is the beginning of the investigation of the Mubarak family?
KASSIM: Definitely, yes.
HOSNI MUBARAK: (Foreign language spoken)
AMOS: His statements are not likely to satisfy Egyptians. The prosecutor's summons is just a start, says Dr. Mahmoud Shafy, a physician and member of the Muslim Brotherhood. That's why he joined the mass protest on Friday.
MAHMOUD SHAFY: We'll wait and see. That's all.
AMOS: So being question is one thing, being charged is something else.
SHAFY: Yes, of course. That is why you have to wait.
AMOS: As Egyptians wait, tension over the strategy to force political reform has caused a generation gap within the opposition.
KASSIM: Frankly, I really disapprove of what a lot of the protestors are doing right now.
AMOS: Hisham Kassim says that a small group of protestors who are now camped out on Tahrir Square provokes the military and endangers the revolution's gains.
KASSIM: I really don't get the rationale of two, three thousand people thinking that they understand the situation more than the rest of the country and that they are representative and insist on my way or the highway.
AMOS: On Saturday at dawn, two people died and more than 15 were injured when the military tried to sweep the small encampment. The Revolutionary Youth Council condemned the violence but they stopped short of directly condemning the military, says councilmember Sally More(ph).
SALLY MOORE: 'Cause it is the only one institution that is holding together so far. So of course nobody wants to topple that. And of course we are, yeah, we're walking on eggshells. That's the problem now.
