From Monday, three discreet TV cameras will offer anyone with an internet connection a front-row seat to a criminal trial of global interest. One of those cameras will be trained on Derek Chauvin, the former policeman accused of killing George Floyd in custody. Mr Chauvin could be jailed for decades over the 25 May, 2020 death of Mr Floyd, an unarmed black man. The knee Mr Chauvin placed on Mr Floyd's neck was filmed for all to see. Angered by what they saw, protesters worldwide said it was time to end racial injustice. Now cameras will let them see the justice system in real-time.Never before has a judge allowed cameras to film a full criminal trial in the state of Minnesota. This access was granted to Court TV, a US network best known for its slick yet lurid coverage of criminal cases in the 1990s. Its "gavel-to-gavel" footage will be shared with media outlets and broadcast live to audiences globally.Every move Mr Chauvin makes, down to the faintest facial expression, will be open to public scrutiny. During the jury selection, which was also filmed live, a suited Mr Chauvin was seen day after day, listening intently and taking notes.While not unusual in the US, that kind of transparency raises long-debated issues about the role of cameras in courtrooms.There are two sides to this debate which both hinge on two fundamental tenets of the US constitution: the freedom of the press and the right to a fair trial.Court TV believes its coverage of The People vs Derek Chauvin will uphold both of those constitutional rights.
