The Shar's CIA trained secret police, SAVAK, tortured and murdered thousands and yes, they raped prisoners.

The Federation of American Scientists reported their torture methods included:

"electric shock, whipping, beating, inserting broken glass and pouring boiling water into the rectum, tying weights to the testicles, and the extraction of teeth and nails".

so nothing changed then, hasn't it? except for the addition of some cruel medieval islamic punishments and the occasional intentional blinding of protestors
