Legality of Boro's actions
Most of the focus on spygate has been around the EFL's rules and potential sanctions - for obvious reasons, ie we care about the football implications.
But one thing just occurred to me. Boro officials "forced" the supposed spy to delete the footage from his phone. How exactly can you force someone to do something like that other than threatening them, through actual or implicit threats of violence? Assuming that's what happened, isn't it Boro officials who actually committed a criminal offense? Which would be a police matter of course
(See eg this guardian article from 9 May that was among the top Google hits when I was trying to find the reporting on this):
"Boro officials forced the alleged spy, thought to be in his early 20s, to delete the mobile phone footage he had filmed the club remain concerned he had the chance to watch Hellberg’s dead-ball routines and they fear his recording may have earlier been downloaded by an office-based colleague."
