Germany (catch all, incl. terrorism)

It's furthermore known that many people in far right wing groups are hired by domestic intelligence for reporting.

So basically if you tell your own (brown) people, you could just as well send a propagand avideo to a TV station. That bunch of loudmouths with little brain is not going to keep a secret.

Which makes me wonder if they even showed the videos to anyone else at all?

If their videos implicate them in the murders as articles say, they were would have been exposed to both informants and cyber-monitoring if they disseminated the video over an internet forum. In addition to domestic intelligence there may be private groups that conduct these activities as well; such is the case in the US.

Which would lend credence to:

My guess is on simple sociopaths. They probbaly justified their criminal live with some ideological BS about fighting against some BS threat.
