Im not one of these Peta geeks or wack jobs- but this does not make sense. A 50 cal although formidable is not a whale gun. It would be like becuase my culture has involved deer hunting since I was young to go out with a bb gun or 22 cal hunting. Sure if real real lucky the animal might go down. Most likely its just gonna get pussed up because of wounds and die from complications. They should have just went to the trading post and bought a can of salmon and sat around smoking the friggin peace pipe. Stupid attempt with stupid results. The indians lost in this and the whale. Mostly the whale.
You're right about that. This reminds me of a documentary which included the fate of an Orca or Killer Whale which had been shot with a common caliber hunting rifle. Eventually (weeks?) it died from complications.
They line speared it first. The traditional way is repeated spearing afterwords. The 50 was used instead of the repeated spearing, because it's much quicker. They didn't finish and retrieve the whale, because the coast guard interfered. Notice the whale died shortly after the coast guard came.
