Because egyptain were subjected for the past 30 years to brutality & harassment by the tyrant thugs (aka police) & corrupted NDP party. Poverty & illiteracy Have also contributed.
The egyptain people revolt now came as a surprise to the tyrant and his corrupt party.
Egyptains don't care anymore
They overcome it, two days ago an actress who was among the protesters told Aljazeera we have nothing more to lose we want him out
Today they shutdown Aljazeera office and managed to remove it from air in NileSat, and yet Egyptians are out protesting today also
