I am a dog person, but if my dog attacked and killed someone, then it has to be put down.
That argument is out of context.
If you are camping in the outback and a dingo steals your baby... do we start baiting and culling adult wild dingos?
If a bird gets sucked into an aircraft engine, causing the plane to crash and kill 200 people... do we start killing all birds?
If someone eats a green potato and dies, do we ban the sale of them?
What if someone snorts too much nutmeg, hallucinates that a giant purple dildo is chasing them with an intention to sodomise them to death, and while looking over their shoulder to see if they are getting away, run head first into a concrete wall. Should we ban the sale of nutmeg?
Since records began in 1791 there have been 217 fatal shark attacks in Australia, that's an average of less than 1 per year.
Now unfortunately, WA has had quite a few deaths (relatively) in the last couple of years, 3 in 2011, 2 in 2012, and 2 in 2013, however lets place this in context.
There are roughly 20 deaths every year from lightning strikes in Australia. Maybe everyone should walk around in a Faraday Cage whenever outside.

It has been sold all over the world.
Colin is worried that we will have tourism issues because of it, as one of our biggest attractions is our beaches.
So, being a typical politician, he has ignored all facts presented to him by researchers and scholars, and has probably jumped to the conclusion presented by some numpty advisor that probably couldn't spot the difference between a Bala shark and a Grey Nurse.
This is no different to Abbot believing climate change is a fraud because his top climate advisor is a well known and outspoken climate change critic, so any research presented to him is based on a biased viewpoint.
