First learn the law of your country. The line of succession is president, prime minister, speaker of the parliament, etc. In the event of the deaths of president and prime minister does the speaker become the president. Haji Mukhtar never became president because the prime minister was alive and in control of government. Cigaal however never became president because he was not confirmed as he was too busy playing qamaar and drinking his heart out in Las Vegas at the time of the murder.
You contradicting yourself, in one way you saying Cigaal wasn't available and didn't want to become president, and in another way you saying he is suppose to be president after Cigaal.
Cigaal wasn't there, so he took the helm temporarly, and you can deny all you want, and cover up that your uncle took the presidency by force from a Rahaweyn man.

What law is there, did Said Barre did Said Barre presidency had anything to do with law?
