Protestors are in two different groups: the silent crowd, and the agitators.
And the governmental forces are divided into two groups as well: the original police, and some unverifiable militia.
Photos in this set are from both in both. You see peaceful demo of silent crowd which are asking for democracy, and the police near them; and you see agitators fighting with Basij militia.
