I know he can be unhinged but if assignment is very clear and time period very short; Miguna Miguna is the best man for the job.
For simple reason they will not honor their summons. Therefore ending the drama very very quickly
Majority of them will chose to go to exile than face Miguna Miguna led probe.
Miguna Miguna meet all requirements - he is Kenya advocate of 15yrs plus.
So Ruto doesnt get distracted by the fight - Just give Miguna Miguna the job - and proceed to do other stuff.
Miguna Miguna will summon Jomo Kenyatta posthumously
by having a letter delivered to his grave and then go for Moi - if they run abroad - Miguna Miguna will follow them with 100 pages of demands - ohoo boy I can imagine the drama.
And that will be the close of chapter - Kenyans angry will become very happy.
If Ruto fails to satisfy the thirst for anger and blood - he will become a Kibaki - Hustler Revolution would have aborted and been betrayed.
