Merriam-Webster defines amnesty:
The act of an authority (as a government) by which pardon is granted to a large group of individuals.

Technically Amesty probally doesen apply here since nobody is comminting a crime, but i spose dumping carby parts should be a crime.

In this senario/context its a process where people who want to dispose of carby parts can do so without guilt knowing that they will go to a good home,(no punishment for admiting that you were going to dump the parts) and it also allows people within the community (ie datsun1200.com) to gain benifit from it.

Think "the gun-buy back scheme" that Australia had in the late 90s. Owners of semi autos, full autos, and military style firearms were asked to return these firearms to be destroyed.

Now, if you rock upto a police station with one of these firearms, and say that you want to return it (it is now illegal to hold these firearms in Aus without a special needs license), you wont be charged with any offenses rela ting to ownership of said firearm., ie its an amnesty.

Of course if you commited a crime with that firearm, wellthats slightly different....
