I believe history is one of the most important discipline to grasp. Reason being its the only way the present generation and the next and the next can learn what's went wrong or what went right and reasons for that. Just because one is viewed as having messed or "destroyed" the country is even more important to remember him and the reasons why he got it so long.
All that is learned so as to avoid mistakes or impossibilities which had been tried before. And also to build on the those ideals and strategies that have worked well and improve on them.
Just like in Science/research the current scientists build on what the previous one did.
Now a public grave would make such history obvious. So as whoever sees it or visit it they can be prompted to study and understand who was who..
If one was a monster let he be remembered as such but let him be accorded special honour having risen to be President.
Of course personal wishes also matter. Am not so sure but US may have Presidents burial site at Arlington but at the end of it depends on individual preference.
My two cents...
NB: public property was stated in jest but Presidents do affect public/country in profound ways such that they shouldn't just be forgotten..
Discuss.
He should be buried alongside Kenyatta. He's 2nd President of Kenya and that should say it all.
Kibaki (when he dies) be buried next to Moi.
What says it all is what he did to the country during his 24 years in power. The sooner people can forget everything to do with Moi, the better. Future generations can learn a few things about Moi and his rule---to wit, extreme nastiness in the abuse of power---but they can do that without visiting the man's grave site. I can think of only one good reason to have a public grave for Moi: so that people can piss or take a shit on his head.
RV Pundit seems to have the right idea in cremation.
His son is within his rights. Ati public property!
