This is an interesting play by their army. Hold Mugabe in protective custody, rather than arrest. It’s a fine distinction, but it may help the army make their rule stick by making their actions seem ‘legitimate’. If they had shot him, or announce that he was being charged, a portion of the Zimbabwe population might have resisted. And I rather doubt that the Zimbabwe military could fight it’s way out of a wet paper bag.
Looks like the coup was a success.
