Word that Husni Mubarak and his two sons will be held in 15 days detention while being interrogated on corruption and other charges is drawing a lot of attention today. Mubarak himself remains hospitalized in Sharm al-Sheikh, but the sons have reportedly been transferred to a pri8son in Cairo. The Egyptian legal system permits detention without charge for 15 days during an interrogation.
There seems to be a lot of skepticism about how far the ruling military council will pursue the matter (as well as about Mubarak's hospitalization yesterday). But the announcement does, at least temporarily, defuse demands that the Mubaraks be prosecuted.
There are negatives too, however. I can see how other beleaguered heads of state (Salih in Yemen for example) could see the potential of prosecution as one reason not to step down. Ben Ali in Tunisia avoided the issue by fleeing to Saudi Arabia, but Mubarak, by remaining in Egypt, was gambling the Army would protect him. It still may do so; no charges have yet been filed.
