I am not being dismissive. Somalis back home kill using the gun. For example, president farmaajo used to attack his opps with soldiers. We Somalis are not so chill and orderly to the paint of waiting for the opportunity of the person we want to kill get sick. Believe me, if the government wanted her dead, she would have been shot 10 times long time ago.
I don't think the government had anything to do with it. Some are saying she had a surgery of some sort, I wouldn't be surprised if she died because some unqualified doctor operated on her. That's a lot more likely than chaotic Somalis poisoning you when they can just shoot you in the middle of street in broad mid day.
Anyways, the point is, we don't know, and until there's clear prove, you and the others should stop the speculations.
