Greenpeace has some worthy goals, and some very important messages. However, it seems that their main intent is to stop all progress and change, and to half anything that has an effect on the completely natural environment. Overall, their apparent intent is not to move society forward, but to go backward, to a steadily smaller nation, of people who do less and less in the world around them, until eventually they achieve a wilderness with no one present except other Greenpeacers.
The methods they use -- not only in this instance, but almost always --are to disrupt and destroy, to halt progress by various forms of terrorism, to force others to stop rather than convince them to act in an ecologically responsible way. It appears that the airport incident may amount to criminal trespass, or felonious breach of airport security.
Because their tactics are so improper and even harmful, most of us lose sympathy with the motives and objectives of Greenpeace. The result is that, generally speaking, their actions are ineffectiev in accomplishing their ends, and they at best set themselves up as martyrs for their beliefs by going to jail.
