Is a Snit Head
Maybe. Being involved with BLM I don't think is an automatic disqualification. A lot depends on how he answered questions. Now if he outright lied about being involved then that would be grounds for a mistrial. If he was up front, said he takes part in BLM, protested in DC, but he can set any prejudices aside and be fair an impartial then he might have been allowed to stay. Now if he was taking part in BLM protests as a result of this case I think it's a different story. It's impossible to find jurors that didn't know about the case but you need jurors that haven't formed an opinion about the case. If prior to the jury trial he was out protesting because of this case then I think he formed an opinion about the case already.I'm no expert on US courtrooms or laws but wouldn't one of the jurors being involved with BLM and Anquifa be grounds for a miss trial?
I would love to be able to give you a simple answer about this. But to give you that answer I would probably need to see a full transcript of this juror's answers to questions and his jury questionnaire.
