One of the dubious accomplishments of the Islamic Republic of Iran is how much it's succeeded at making criminality utterly banal. The government has made so many prosaic things illegal - from certain hairstyles, to satellite transmissions -- that consistent enforcement is impossible, and hypocrisy is endemic. Rule-breaking is so ubiquitous that Iranians often don't even feel compelled to hide their flouting of the law... So you go into the supermarket, and next to the cashier you'll see a stand holding Hollywood new releases that wouldn't make it past the censors.
Or...you'll drive on the highway past people selling contraband puppies off of truck beds... Dogs are technically illegal in Iran, but in a tacit acknowledgement of the popularity of the puppy black market, the government hasn't barred the sale of dog food.
Running a comprehensive regulatory state is rather harder than most people--both advocates and opponents--realize.
