Jim - I don't disagree or minimise this worthless ****s individual horrifying terrorist attack
as the actions of a lone nutter...

It may only be a small organized terrorist cell,
and they will have direct propagandist links all over the world..
but on a bigger scale they are extreme symptoms of an increasingly spreading fanatical ideology...

I know of at least one rabble rousing 'popularist' youtube channel
based only within a few miles of where I live in our provincial west country...
