AWB50 is a bunch of horse shXt, Whats the point of banning a weapon that has never been used in a crime? Organizations use the terrorism BS
to scare ignorant people into thinking "Oh no Alcada(ment to spell it that way) or the local hoodlums shouldnt be able to go and get one of these ALL POWERFULL weapons of mass murder from just any street corner". They are expensive, big and heavy, no criminal wants a weapon that size, and most couldnt afford one if they did.
Here is a quote from one of the brady bunch from this site http://seattlepi.nwsource.com/national/206444_guns04.html
"They can pierce the skin of an aircraft," said Daniel Vice, a lawyer with the Brady Campaign to Prevent Gun Violence, a supporter of the law. "It could be used to shoot down an airplane. And we certainly don't want to wait until a terrorist buys one before we ban it." end quote
Im pretty sure most rifles could pierce the skin of an aircraft, its just sheet aluminum. And hitting a plane would take alot of skill, they move at a pretty good speed.
