From the link:
“For the 35 years since I founded the Sea Shepherd Conservation Society, I have strived to act non-violently and within the boundaries of the law
,” Watson said. “During Sea Shepherd’s long history, we have never caused a single injury to any person. Although we have broken some bureaucratic regulations like Canada’s so-called Seal Protection Act, we did so to challenge the validity of these regulations.”
From their site .... non-violent and within legal boundaries seems to be defined in an unusual manner, which seems to be the norm with this group. http://www.seashepherd.org/who-we-are/t ... pherd.htmlThe next day, slipping out of port before the authorities noticed, the Sea Shepherd surprised the Sierra drifting just outside. By radio, Captain Watson warned Captain Nordengen of what he was going to do and accelerated to full speed.
The reinforced bow of the 779-ton Sea Shepherd connected with the bow of the 650-ton Sierra and kept on going. Captain Watson circled around and hit the Sierra again on the port side, tearing open a 7- by 10-foot (2- by 3-meter) hole. The Sea Shepherd then slammed sideways into the smaller Sierra, staving in a long section of the Sierra's port-side hull.
Listing badly, the Sierra ran for protection toward some Portuguese naval ships. The Sea Shepherd headed for Spanish waters, but a navy ship overtook the Sea Shepherd and convinced Captain Watson to return to Leixoes.
In early November, 1979, without a hearing or trial, a Portuguese judge awarded the Sea Shepherd as damages to the owners of the Sierra. (Some inquiries suggested that the judge had been bribed by a representative for Andrew Behr). Afraid that the Sea Shepherd would be converted to whaling operations, Captain Watson and his crew scuttled the Sea Shepherd on the evening of December 31, 1979, by opening the sea valve in the engine room, and even though it pained them very much, sent her to the bottom.
The Sierra had been towed to Lisbon for repairs, though the Portuguese authorities lied to the American consul and told him that the ship had left the country. Taking advantage of the Sierra's immobility, a team of underwater demolition experts made preparations to finish the career of the whaler.
