PUBLISHER'S LETTER Why shouldn’t the Internet be censored? Just recently, the NSW Attorney General, Jeffrey Shaw, has announced the intention to draft legislation that will make it an offence to transmit or receive material unsuitable for minors over the Internet. Predictably there has been a howl of outrage from the civil libertarians who seem to argue that any censor­ship, on any media, is an attack on free speech. They also argue that censorship of the Internet is technically unworkable. Well, I’m not so sure about either of those arguments. On the subject of free speech, it always seems to me that the people making the loudest noises are often defending the availability of pornography. In other words, their arguments are tendentious – they either want pornography for themselves or they want to make money by selling it. While most pornography probably is harmless, do we really want it even more widely available? There is also the argument that it is up to the parents to see that their children are safeguarded from pornography and that adults should be able to make their own choice at all times. Both of these latter points look quite reasonable but they are made by people who apparently don’t have much experience with children. While it may be relatively easy for parents to prevent their children from seeing particular videos at home, it is not nearly as easy if undesirable material is available on the Inter­net. How many parents are able to watch what their children may access at any time via their computers? Remember too that more and more schools have access to the Internet both in the classroom and in the libraries. Can we have constant vigilance in this regard? It’s impossible. On the other hand, it would be entirely workable for a government authority to maintain a constant watch on what was available on the Internet. If you and I can use a “web browser” to search for particular material on the Internet, then so can a government authority. They could do it 24 hours a day. Once they detected undesirable material, they could pounce. To my mind, the real question concerning the need for censorship on the Internet is whether we need any more legisla­tion. If pornography on the Internet does not involve paedophilia or serious violence then probably little should be done about it. After all, children will be exposed to this material sooner or later as part of growing up. On the other hand, if material on the Internet does involve serious violence or paedophilia, then surely existing legislation is adequate to stop it – it merely needs to be enforced.
