Australia attacks

I just watched a video about a third man being killed by a shark attack in the past two months in Australia. Now, there is a massive hunt for this "man-killer" that boats are lining up trying to bait in the great white shark. First of all, it is so sad that three men died, however, it would be IMPOSSIBLE that there was just one shark responsible for all three deaths and even harder to prove which one did it. Furthermore, how in the world can someone positively "ID" the shark that is responsible for the attacks. It's not like these sharks have ID cards that they can flash to people on the boats.
It is false to think that once a shark has tasted human blood that it is thirsty for more. That may be true for other animals but it is CERTAINLY NOT TRUE for sharks. Sharks are notorious for attacking due to mistaken identity. Once the shark realizes that it's prey isn't a seal, fish, dolphin, etc...it USUALLY swims away. It has been proven that sharks DO NOT like the taste of human blood or flesh. We are too bony for them, which is why majority of the time, once the shark lets go it doesn't come back for more. The problem is considering these animals' massive size, one bite can be devastating to a human, which is why people often lose limbs or die.
I cannot even imagine what the families must be feeling and I give them my deepest sympathies, but I do not think the answer is to have a bunch of fisherman trying to kill all kinds of sea life when they have no idea which shark or sharks attacked those men. Isn't bad enough that we lost three men, why do we feel the need to justify their deaths with mindless and needless slaughter of (MOST LIKELY) innocent animals?
Mindless killing is definitely not the answer and most definitely will not "teach those sharks a lesson."
