Lawyers love nondisclosure agreements. We like to control discussions, particularly anything that anyone says about our clients. Nondisclosure agreements, however, are not always a good idea. One time that they are a bad idea is when a youth sports league is talking to parents about the arrest of a league coach for child abuse. According to news reports, officials in Saskatchewan charged a youth softball coach with sexually assaulting a minor. The league suspended him, and then invited parents to a meeting to discuss the situation. Such meetings are common and usually a good idea. Youth organizations have a moral (and sometimes legal) obligation to be transparent with their clients and parents.
What is most definitely not a good idea is what the officials did next. As parents entered, the officials asked them to sign nondisclosure agreements. When parents protested, a meeting leader said that they were trying to prevent discussions in the media. Avoiding discussions certainly is a laudable goal, but it's a pipe dream. When something this incendiary happens in a youth-serving organization, there is no way to prevent rumor and gossip, or comments to the news media. All an organization can do is figure out how to respond to questions.
I don't know who thought of the nondisclosure agreement, but it sounds like a lawyer trying to go to his or her usual toolbox. In these situations, however, the usual lawyerly tools don't work and can simply make the problem worse. It's rarely a good idea to let a lawyer run your public relations strategy.
