Unable to control Iranians seeking 'democracy, human rights, and secularism', the regime regularly imports 'Arab mercenaries' from surrounding countries. Here are pictures of the'moral police' roaming the streets of Iran, speaking 'Arabic'.
Some may have a difficult time telling the difference between Iranians and Arabs, but Iranians can spot foreign Arabs from a mile away usually based on facial bone structure, and mannerish.
Regarding the photo of the security forces in Iran, I just heard from a student in Iran...
"Doc, I can tell you as an Iranian that these guys are from Egypt or Northern African countries. They are not Iranians definitely."
The regime has to import foreign security forces because the regime cannot trust it own people to keep control of the country.
