I don't have any solid answer for you, but everything I ever heard Vernon was destroyed emotionally by the death, He had a long couple of days, probably a million things on his mind. Just a guess but He probably just wanted it over with so he could deal with losing the last member of his own family on his own. I've never really heard of any other celebrity dying and the fans being allowed to walk in the house and view the body in state like that besides Elvis.
Not to mention the danger factor from your quote and that some fans were Killed out front that week by a car and it had to be an extreamly stressful time. Plus there were probably staff members and grounds keepers and the Colonel and so on and so on in his ear expressing condolences but probably also asking "What does this mean to me, do I still have a Job?" and he had to make some of those decisions too.
