There is no way to protect whistleblowers from retaliation without anonymity. Clearly politicians want to perform character assassination on whistleblowers. Some members of the
public and media will crucify this person. A whistleblower brings up the concern, they are not the accusers. An investigation determines if the concerns are founded then the federal government files indictments for any criminal acts. The Federal government is then the accuser, on behalf of the American people.
