This is not a new demand for the protesters, from day one, the chant was "down with the system" and "we want the system to fall down". Mubarak was a symbol of the system but not all the system. 'Mubarak to step down' was just the first item on a list of demands including releasing political prisoners, the immediate stop of emergency law, the trials of those who ordered the killing of protesters in the revolution and changes to the constitution among other things. The old regime is still talking about "a movement" or "dispute" or "demand for change" and they can't see it as a REVOLUTION. People can not and will not accept Shafeek and his men to run the government even temporarily, as they were picked by a fallen president and they were in charge when men and women were killed in the streets after asking for freedom.
The demands were and are clear, We want the system to fall, nothing more nothing less. The system means, the current government, the governors all over the country, head of the police and the secret police, media directors who served the system and all their men who are scattered all over the country.
It took 18 days for Mubarak to understand the message and I can understand that after 30 years in power, he became a little hard of hearing but he heard at the end non the less. I am sure that the current government under Shafeek's leadership may find it hard to hear people's voices, but they WILL hear it sooner or later.
So..Celebrate, Protest and Keep the pressure on.
Long Live Egypt.
