Do they have the equipment to do this? Mullahs will slaughter them if they do not. I don’t know what the situation is there. I know in Gaza and Iraq they could do it because the idiots are always “celebrating” with said equipment.
If you had several hundred thousand people with sticks and knives, fighting in tight urban terrain against several thousand riot police, most of the city would fall to the protesters immediately.
Once you start bringing in tanks and machine guns, it's a different story. For both sides. Because Iran doesn't know for sure who the tanks and machine guns are going to side with, if push comes to shove.
