'bit of pressure' ?? Think they would have subjected him to more than that. In the 1980s the police were out of control this is why recording of interviews was brought in. You have no idea how they really spoke to him during these interviews and outside of the interviews.
For someone who claims to have an open mind you seem to be very certain Jeremy Bamber is guilty imo
The wording of the interviews seem fine. Questions relating to Jeremy, Mugford, the gun, Neville & the night in question. Jeremy had a lawyer with him. All the police could do is raise their voice, which I am sure Jeremy could handle.
Jeremy has never claimed the interview transcript is wrong or that he was bullied at all.
