I have a hard time believing that an actor hired by a company like Disney, would do such a thing on purpose. I've dressed up as a mascot character once for a children's event and let me tell you- you can't see, hear, you are burning up inside, your balance is way off, and all you hear is mumbled kids yelling at you from all angles.
When I was three and went to Disney- I was snubbed by Mickey Mouse himself! I ran up to Mickey crying "Mickey! Mickey!" and I was anxious to have him hug me just like the other kids. Except that when he moved his head, his ears whacked me in the temple and I hit the ground. I cried and cried and thought that Mickey hated me. But you know what... in retrospect, the character's handler should have seen me and then guided me to stand in front of Mickey in that very SMALL window of vision the actors do have.
Still, if a court decides there is enough evidence that this actor did something so blatant as the article states.. well, let the chips fall where they may.
