Donald Trump’s history-making criminal trial is set to start Monday with a simple but extraordinary procedural step that is vital to American democracy. A group of regular citizens — Trump’s peers, in the eyes of the law — will be chosen to decide whether the former president of the United States is guilty of a crime. The process of picking a jury could take a few days. Lawyers on both sides of the case will have limited opportunities to try and shape the panel in their favor. The court will seek to get people who are willing to put their personal opinions aside and make a decision based on the evidence.
