From a NIAC reader:
One close friend of mine worked as election official in Shiraz. He says they received 70 ballot boxes, in which 40 of them were with broken seals. The answer to the question of “why the seals are open?” was that the boxes move in the car during transit, so the seals came off. He says the votes in the 40 open boxes were all for Ahmadinejad and Mousavi was leading in the rest of the 30 boxes.
