I am going to outline what I think happened....
1. Family is online waiting to greet Tigger. When their time comes, they send the two little boys first.
2. Fast pass photographer offers or is asked to do a family picture so Daddy tried to get into the picture. He is being aggressive to Tigger, as evidenced in the YouTube video where he says something about getting Tigger's head. (I assume he grabbed Tigger tightly or hit him in the head, can't tell cause you can't see, all you see is the ground.) Tigger had to make a motion to him that he was being rough cause the guy says sorry, but with some sort of sinister laugh.
3. Daddy gets out of the picture and makes his I'M TOO OLD FOR THIS CHILD STUFF son get into the picture. The kid grabs Tigger's costume, trying to be all tough guy like, and the CM feels his air cut off.
4. CM signals to attendant who is turned around or just not paying attention. He signals cause he was always roughed up by daddy, now he is getting roughed up by SONNY. Tigger was looking for the attendant to settle the family as he knows he cannot act.
5. In a self defense move, just as his head is pulled back, and the mask almost ripped off, the CM locks the boy's left arm, to gain balance, and he turns around to get free. Since he was always roughed up by daddy and now the son, and the attendant was not coming to his rescue, this was his only logical move. Free himself.
6. CM lifts his left arm up so he can grab the kids arm and help free himself, and he accidentally brushes the kids face. The kid then acts out in his teenage rage and slugs Tigger in the face. (Apples don't fall far from he tree. Daddy and son have temper problems, bully issues, and other issues I shall not get into.)
7. Family leaves the area and watches the video. They proceed to ride RNRC, TOT and STAR TOURS. Daddy starts thinking TIGGER SLAPPED MY SON!!! YES I AM GOING TO BE A MILLIONAIRE!!!!!!
8. He tells a CM or Guest Services who alert management. Of course, Daddy only shows Tigger slapping his son, not what they did first.
9. Managers apologize. Family happy, they enjoy Fantasmic and leave for the night.
10. Next morning they enjoy another day at the parks, riding other rides.
11. Son complains of neck pain the next night. Daddy sees $$$ and takes the kid to the hospital. Of course, the neck pain didn't come from riding any of the wild rides, or maybe sleeping wrong. The pain is cause by TIGGER slapping him.
12. Sunday rolls around. Daddy trying to get his story straight so he can get MONEY!!!!! Calls the sheriff's department and makes a formal complaint. Red spot on sons suddenly appears since it wasn't there when the NEWS MEDIA interviewed them.
13. New media contact them for an interview cause they can now BASH DISNEY!!!!! Funny, no red mark on the kid's face. They claim they only want an apology, for TIGGER to be a man and apologize. The media plays the part of the tape the family and media WANT YOU TO SEE. What happened to the part where the father roughed up Tigger??? Maybe hanging out with the Kennedy magic bullet????
14. After continuing to state they ONLY want an apology, the family quickly hires a lawyer and appear on morning shows on MONDAY.
The incident happened Friday. BY Monday they had a lawyer and appeared on morning shows. Funny...... they moved pretty quickly for only an apology... NOPE!!! now they want money.. Now they say they are suing.. Wow... Sunday and Monday they only wanted an apology... TUESDAY they want money.... HMMMMMM
