All I got from this film is that Sea Shepard is totally useless.
Trying get outlaw fishermen back to port to face trial is a waste of time. Jam their radio and gun them down. Ram them and sink them, leave no trace of their existence. Then move on and find the next next one and repeat.
That is what we should be doing with the Somali pirates as well.
That doesn't make them useless... it makes them not killers. Sea Shepard would be useless if they all got arrested for murder and therefore weren't able to go out and challenge more outlaw fishers. I think that even if it's a little less effective, they're probably doing more good in the end by making many fishermen's lives more difficult and hopefully landing some of them in jail, rather than killing one or two and then being put away for life.
Let's try and be reasonable here. If they went around kiling people, they wouldn't be any better than the men who go around killing animals.
