Iranian gun laws bleg:

The Small Arms Survey suggests that Iran's per capita gun ownership rate is 0.053 (that is, about one gun for every twenty people). This is fairly low by global standards. (See Tables 6 and 7 of my recent article in the Texas Review of Law & Politics.) Could commenters please supply information about the gun laws of Iran, and how they are enforced? What kind of people in Iran are allowed to own guns? What kind of guns? Please don't get into a discussion of whether the Iranian protesters would be better/worse off if they had guns. Just supply accurate information, with citations if possible. Comments based on personal experience from people who have lived in Iran, or visited Iran, are welcome.
