No, this is fake and gay. Law anon here. It's captioned (meaning the title of it, "who vs. who") is civil. If it's a criminal prosecution, it will be "The United States" or "State XXX" vs. the defendants.
And civil cases don't get grand juries, that's criminal cases only, and grand juries issue indictments that START cases - you don't file a case and then ask for a grand jury to indict. This is a hoked-up sham.
Total bullshit.
