This NPR Story highlights the problem that the exchange of information represents in a country under a totalitarian government. Information is a threat to established power in Iran. Information in and information out. But as you can see from this story, instead of shutting down that pipeline altogether, they are using it to identify those in their country that they feel represent the biggest threat to their power.
There are stories that are making the rounds of arrests and even executions in Iran by the government of those who are considered in opposition the those in power. If even a portion of these stories that are getting out on Iran are correct, this is a terrifying time and an affront of humanity in Iran. I believe history will judge this government harshly.
