Exactly.Aside from the fact that there’s no way to tell that it’s actually him, or what really happened, it would never be admissible in court.
There's no way that "girl fight" video gets introduced at the trial; it can only be used to convict Kyle in the court of public opinion.Unfortunately while it does have nothing to do with this shooting, the prosecution will argue to have it included to demonstrate that Kyle is a monstrous woman beating, racist, bigoted, white supremacist. This will be found relevant to the establishing his intent to murder peaceful protesters and the defense will still have to deal with it. But yes, complete and total bullshit.
