Don't understand the patronizing tone here. For a start, the BBC Q&A I've read on this says that it's basically the Swedish prosecutors saying, "No, because of circumstances, we want him here", not "It is legally forbidden". The prosecutor saying "We want him here, and we aren't going to tell you why" doesn't exactly radiate fairness and transparency.[1]

Maybe I'm wholly mistaken, but it stands to reason that should be a legal possibility that an individual can be questioned over video link. For example, consider a Swedish invalid who is in delicate condition in a London hospital and is medically forbidden to travel.

"Karin Rosander of the Swedish Prosecution Authority told the BBC on 21 August 2010 that "because of circumstances in the investigation, [the prosecutor's] opinion is that it is necessary that he is present in Sweden".

Ms Rosander said the prosecutor had not made clear exactly what those circumstances were. "At this stage of the investigation, [the prosecutor] does not want to specify," she said."
