There was an investigation into a problematic workplace environment. This particular lawsuit is claiming that there was an organized effort between the commissioner of the NFL and the owner of the commanders to mislead those investigators during their investigation. Should we be ok with our government investigating on behalf of citizens who report a workplace for putting employees in harmful situations? Of course we should. If, during the investigation, the investigating body finds evidence of the workplace purposely sabotaging the investigation should we be ok with our government suing the workplace over it? Of course we should. This is the purpose of government, to protect it's citizens. I think you lost focus of the situation here.
