At the risk of putting a damper on an otherwise good idea...shouldn't the actual petition say something better than "Remove ASIC cards entirely." I know if I was a politician I wouldn't place much importance on a statement like that. A bit like saying "Remove speed limits entirely". Surely you need to make a case on the grounds of saving taxpayers money, public perceptions of safety, restrictions on rights etc etc.
It would be better to do a bit of research and to speak politicians language in terms of money, risk and public (or media) perceptions...such as:
Country X has a lot higher risk of terrorism but they don't have an ID card
60 tonne B-Double semis pose a far greater threat to airport safety in terms of what a terrorist could do than a 600kg aircraft. Truck drivers don't need ASICS.
The costs outweigh the benefits
Studies show that......
It's unconstitutional because it restrict trade between the states ( )
etc etc
In any case, in this day and age of interconnected information, I can't work out why a "background check" is needed any more. Surely if Joe Bloggs commits a suspicious act any law enforcement agency could look up a file and see that "Ah ha, Joe Bloggs has a heavy vehicle drivers license, he has a permit to use certain fertilizers, he has a firearms license, and horror of horrors, he has an RAAus CERTIFICATE!!....bring him in for questioning!!"
