Disney gets hit with a devastating blow from which it will never recovers and is forced to close it's doors by the end of the decade. Walt's conviction would forever be remembered as the death of America's innocence, and is considered one of the darkest events of the already traumatic 60's. The movies are forever tainted, and the world today is a more cynical and depressing place.
Like I said in my last post The Walt Disney Company goes under in the event that Walt Disney was convicted of such crimes against minors and here's what also happens.
1. Disneyland gets demolished after the property is sold.
2. All the Movies and Cartoons produced by Disney likely disappear from circulation (Even redistributing them with the Disney logos and all references to Disney completely removed will be controversial) as they will be tainted.
3. The Disney name becomes permanently tainted.
4. Mickey Mouse and all the Cartoon Characters created by Disney would never be seen again in any medium or form.
The long term effects this has on the world would be difficult to figure out (But the world today will not be the same in general and there will be negative long term effects).
