It means they will continue if they find out that people who should have reported did not and were covering up.
Covering up what though? A systemic pattern of brutish behavior? Something horrible and completely harmful? Or gossip and innuendo without knowledge or actual witnessing anything substantial? We don't know anything in the absence of detailed information, which none of us have right now. So, let's not equate these allegations with horrific abuse, unless and until that's proven. And I don't know why there's a suspicion of something being covered up. I would hope that any skater who actually witnessed something egregious would have spoken to the perpetrator and the victim in an effort to get help for them both.
Some of the most horrible abuses occur in families, where it's never reported. Or there's horrible rape and/or bullying which can occur to a minor who never reports it to their parents until sometimes the parents find out 20 to 30 years later. Read the memoir,
Hunger by Roxane Gay; read the memoir,
Educated by Tara Westover. Read and weep, and then give thanks for your own life's blessings.
Meanwhile, we don't know what the allegations against John Coughlin are. He's dead now, and I personally do not want to see anything swept under a rug. Let it all be revealed, while keeping the accusers' identities anonymous and protected. Let us stop and reflect on all the various human interactions we've experienced in our own lives which might have been uncomfortable and inappropriate, or unfortunate but that did not involve horrific physical abuse or result in someone killing themselves. There's no way that death should have happened.
For the skating community and for all communities, there needs to be education, communication, counseling, mediation, and an opportunity for understanding, reconciliation and rehabilitation. In instances of premeditated, systemic and uncaring horrible abuse, or an egregious pattern of harmful behavior, that needs to be uncovered and dealt with quickly, thoroughly, and harshly. But what was it that happened in this case exactly?
