With enough folks they can get the guns that would be used against them. Dictators will always fail if the folks turn on them and that IMHO is what is happening. The mullahs would do best to just get out of town. Of course they probably won't so events will follow their course like gravity. There are guns to be had they just have to be taken.

Dictators fall when their security forces, particularly the army, turn on them.
They remain in power as long as enough armed people are willing to kill others for them. Power grows out of the barrel of a gun, in the final analysis.
Which is why who controls the guns is so critically important.
