I agree. Apparently, he was in Texas to go hunting, not a sport for an infirm man.
Better to just do the autopsy.
The only advantage to not doing the autopsy would be a possible public outcry of conspiracy. That would justify holding up any appointment of any replacement.
You can’t have a suspicious death, a suspicious burial, and then allow a nation-changing decision to be made by a radical who was on the exact opposite side of the law as the deceased possible victim.
Many will still call for a conspiracy even if an autopsy turned up heart attack. I don’t think the government should be in charge of that decision in the first place. Obviously the family doesn’t believe anything sinister happened. Wouldn’t they be the FIRST to have suspicions?
Sounds as if he was a heart attack waiting to happen otherwise his own doctor would have pushed the family to have his death checked out. JMO
