From what I gather, the person had a baby stroller and the bus driver told him that he had to fold it up before entering the bus. Everyone crammed forward and filled the bus before they could board and then with the bus being full, the driver told him that the bus was full and that he would phone for another one. At this point the man literally threw the baby at the driver., the mother grabbed the baby and then the man repeatedlly grabbed the bus driver by the throat while all the bus driver did was try to defend himself. Never once did he go on the offensive. On the video I saw, he did an outstanding job by not getting overly involved....but I am surprised that no one else tried to defuse the situation but I have read on a thread that the third person in the group (on the video) was actually a Disney security officer that was riding the bus. From what I gather from reports, the man was charged with assault, child endangerment and will be banned from Disney for life, but as you said, it truly was an unfortunate incident, not only for the assailant, the bus driver but all the riders on the bus, especially the children who had to witness this at "the happiest palce on earth"
