This is a perp walk, the police/DA/et al made this happen - and ensured the media was there to capture the moment of him in ‘inmate orange’ flanked by heavily armed state police. Absolutely pre trial prejudicial influence.
Given the speed at which his arraignment and extradition from PA happened, and the fact that the NYPD could have chosen multiple different routes and methods to get him to NYC, he could have been shuffled into a regular prison bus in a police convoy from the airport, with blacked out windows - like is common in Europe where this kind of malfeasance actually results in mistrials and acquittals.
Step into the arena, many many people far smarter than you or me have hashed this debate and still have no consensus.
