There have been legitimate cases. However the lobster fisherman do not consider it a valid case unless a whale is found with ropes in it that have imprinted on them “this rope belongs to Billy Bob and he meant to kill this whale.” We know there are rope mortalities. We know the population is collapsing. Lobster people opposed the regulations that would reduce rope- because they would be expensive. Private businesses decided they no longer wanted to buy those lobsters then- making the lack of action by the lobster industry way more expensive than reducing the ropes would be. In essence they screwed over themselves.
