Because many citizens, ignorant of politics, expect miracles from the demonstrations for Tempi or any other issue, it would be good for them to know certain issues of political sociology.
No government falls on its own because thousands of protesters take to the streets. Also, any systemic parties that participate in the demonstrations wish to maintain the rotten regime.
For fundamental political change to occur, the protests must aim to elevate the political consciousness of the People to the point where they gain such confidence that they take for granted the signing of popular decrees that will annul the decrees of an unpopular government.
