Jaramogi believed in some policies which at the time were toxic. More like Socialist. And that in itself was a grave sin to the Americans and Brits as they engaged in mortal kombat with USSR and Socialist/Communism ideology. And given Jaramogi's tendency to not hold back his opinion he was considered dangerous.
To be honest I think CIA manufactured a lot of propaganda to get rid of him and therefore most of what he was accused of was designed to achieve that end. I also believe IF truly some tangible evidence had been found to link Jaramogi to such plots, Kenyatta or CIA would have had killed. No doubt.
For '82 Coup, I read some participant was quoted as stating that Jaramogi had warned his son Raila not to get involved in such. How far he himself eventually got involved am not sure.
Kenyatta had his own political motives to demonize Jaramogi as the latter was vocal and critical of Jomo's thieving at a time when no one asked any question.
Also Raila had disputes l, for example, with his father on running of Ford-K as Jaramogi was not considered brave or radical enough.
So CIA made Jaramogi stage or attempt all those coups? Including 1982 where he was aware. You know Jaramogi spent a lot of time in prison (house arrest) because he was like Raila now - a community leader - but he attempted with help of Russians, Cubans and Chinese to overthrow kenya gov severally.
It shows your little knowledge of history.
Anyone who did not sing the American song in the 50's till 70's was under CIA radar. Only the American puppets like Jomo Kenyatta were left out and nationalists like Julius Nyerere were left out. Today one can see the results of Jomo's betrayal to his people with the ethnic thinking of most bloggers here very intrenched in their DNA.
