Agent A. If I may, and with respect to Dave M comments especially, point out one thing.
There is a confusion between their MOTIVES and ABILITIES. I think it very contraversial to argue about the merits of whale hunting. For my part, I agree with you totally. It is a barbaric practice that nearly all nations have boycotted.
However, if you are asking about the conduct of the sea shepherd crew, than that is a totally seperate issue. I personally don't think they are doing the anti-whale hunting cause any good at all. I don't really have a lot of time for Greenpeace either (too political) but at least they act in a more professional manner.
However, that this discussion has reached 3 (soon 4?) pages means that the shepherd crew has done something useful... they have got people TALKING about it- which is a laudable achievement.
