1) Technically, he said "it sounds like this could be planned by Disney." He didnt accuse anything, simply suggested it.You can't prove a negative.
Unless someone has something (even circumstantial) that suggests other than what was reported, we should just go with what was reported rather than accuse Disney of staging things. I say this for two reasons:
1) It's technically libelous
2) People will point at you and laugh
2) People pointed and laughed at some histories greatest men and women.
