My view of right response
1. Kid is banned from locker room and any access other than as a paying customer. He can buy a ticket to a game, but he cannot come on the field or into the locker room or into the practice facility. He is banned. If dad is unhappy about son's ban, dad can find a new job.
2. Dad gets a severe warning but isnt fired. He is responsible for his kid - especially when he brings the kid into the locker room. The locker room wont happen again, but Dad should be told that kid cant be a further source of jets news. Period.
