Hillary Clinton said it's "worth considering" a nationwide gun ban and a "buyback" program to eradicate private gun ownership.

The presidential candidate attacked the Second Amendment during an Oct. 16 town hall meeting in which she was asked if it were feasible for the U.S. to confiscate millions of firearms in a year.

Hillary said:

You know, Australia's a good example, Canada's a good example, the UK's a good example. Why? Because each of them had mass killings, Australia had a huge mass killing about 20 or 25 years ago. Canada did as well, so did the UK. In reaction, they passed much stricter gun laws.

In the Australian example, as I recall, that was a buyback program. The Australian government as part of trying to clamp down on the availability of … weapons offered a good price for buying hundreds of thousands of guns and basically clamped down going forward, in terms of having more of a background check approach, more of a permitting approach.
