Here is the Crown's press release following their sentencing, describing the material in their possession.

Their arrest was widely reported at the time. Here's an article from the BBC after their sentencing, in which Todenhoefer's lawyer says:

Timothy Green, for Emde, told the Old Bailey that his client had become a Muslim in 2003 and that he had opposed the invasions of Afghanistan and Iraq. He had been the moderator of a website for people who shared his views.

At their first two appearances in court, the two men refused to stand. Both men said standing would be an act of worship that went against Islam. But Mr Green said that Emde now regretted the offences and had had a "very difficult six months in the UK". He spoke no English and had received no prison visits. No prison clothes could be found to fit him because of his large size, Mr Green said.

He had no desire to stay in this country any longer than he had to and wanted nothing more than to be sent back to Germany.

Mr Green added: "Mr Emde is not a terrorist. He was not going to pass the documents to anyone.

Emde reportedly lived in a radical Islamic mosque after leaving prison in Britain. He now uses the moniker Abu Malik al-Almani.

Also interesting is that Todenhoefer tells CNN he knows Emde well, having gotten to know him over 7 months during which he spent 14 to 16 hours interviewing him. I wonder if Emde was Todenhoefer's entree into ISIS for this trip -- the one who vouched for him to senior ISIS leadership, resulting in ISIS granting Todenhoefer a written pass and promise of safety during his recent trip.
