He’s obviously been using amphetamines, probably also antidepressants and who-knows-what other drugs for at least the last 3+ years in increasing doses-it is plain to see that. Sooner or later, he was bound to OD because the body and mind can’t handle that forever.
Maybe that is what has happened-he was over-medicated and the handlers can’t get much-or any- of his cognitive function back-not enough to get him to appear like he was the last week or so. If that is the case, I hope some mole gets in and gets that info out to the public-even that evil SOB doesn’t need to be turned into a literal zombie with no one going to prison for doing that...
As good a guess as any.
Or the drugs raised his blood pressure and caused a stroke?
