Recovered video evidence a significant part of a terrorism case

I've posted multiple times about recovered evidence. In summary, it can be the best and the worst evidence - best for value and worst for the quality of what you have to work with. Here is a news report on a case where it plays a significant part in an effort to disrupt terrorist operations.

On an audio/video recording broadcast on TV, the defendent says in Arabic that:

he wants to take revenge for the injustices that Muslims undergo across the entire world. Police found the video tape when he was arrested last October.

The video's message is directed at "the Muslims in Europe, my parents, my brothers in the jails of the despots and the government and people of the Netherlands".

The defendent's words speak for themselves.
