Interesting read, and while I applaud Montoya's continued efforts to investigate the subject matter, it's not easy to see what he's actually recommending here. I guess that boxing writers like him, similar to Walsh and Kimmage in the cycling world, are just trying to keep this issue in the news. God knows there's plenty of people who'd be happier if it went away.
It's also quite difficult to tackle guys like Heredia unless you can access financial records. And you need an extremely strong case plus government backing to do that.
