There was a follow-up video where a guy hooked that particular shark, but his gear was too light. When the shark got bored with the fight, it just bit through the line and went on its way. I don't think the neighbors would react too kindly to somebody setting up a chum line in those waters. Labrador retrievers would be disappearing in droves. Of course, for anyone stuck in a nasty marriage, a bucket of chum is a lot cheaper than a divorce lawyer. (there was a time when I thought a lot about stuff like that)
