Green issues have more backing in the last 10 years than any other time in history, Greenpeace and their stunts have undoubtedly helped this cause.
You call them terrorists, i think that's just you using the language of the gutter press, you might as well call everyone who who protests a terrorist, please remember this was an entirely peaceful protest before calling them terrorists.
Do we all have 'mug' written on our faces; name me one incident in the past where Greenpeace's activities have made a difference?
They're not terrorists, they're protesters and they had a choice to make it an 'entirely peaceful' protest but that is severely undermined when they decided to actively stop a train and cause its driver unnecessary stress.
