My dog became spooked by a judge at a show and is now fear aggressive towards all men. Can this be fixed? Will any of your DVDs help?

I have a male bull terrier I have been showing since he was 4 months old and conformation classes since he was 12 weeks. We go to conformation classes every Tuesday. We recently had been to a show as a 9 month old pup. He was being judge by a man that should have never been in the ring with a puppy. The judge was very rough with him and he got spooked by the male judge and is now fear aggressive towards all men (he will let youth males touch him with out problems). He growls barks and would snap if he got the chance. He never was afraid of anyone before. I have had to stop showing him because of this I just can't seem to get him over it I am just so frustrated. Can it be fixed? Will I benefit from any of your training DVDs? Thanks so much for your time.
