Former gang-banger Albert Gonzales served time in prison from 1970 to 1975 when he was a young man.
He's been running a youth boxing club in the Hemet-San Jacinto area since 1990.
He now wants to help coach his grandson's football team. League officials say 'No.'
Gonzales, who has undergone police scrutiny to work as a boxing mentor with local children, is frustrated.
