Castellano was out on bail if I'm not mistaken? If so he may have had restrictions on him. If he did go, it. would have hurt anyone else who attended. I think he should have been allowed to go, but police, FBI and others along with he media would make as if was a crime to attend the funeral of a person he knew. He was smart to not go, and Gotti had no excuse for being mad, and no place in the mob at the time to question Castellano.
