You did have a buy back in Australia but what happened to those who did not want to sell their weapons? Were those people turned into criminals ans arrested? That is the problem with removal of guns which goes to rights of ownership. Law abiding citizens pay a lot of money for the guns they own and ownership is no different than owning a car, a house or even a TV. Imagine if the government decided that we can no longer own a car because drunk drivers killed too many people. Would that be the right thing for them to do? Why should all people be punished because of the actions of only a few? Why should a few people in our country think they know better than the rest of us and arbitrarily decide "what's best" for the rest of us. Something as major as forcefully taking away privately owned property should not be decided by only a few it should be voted on and decided by the majority. All to often in this country laws are enacted by law makers listening only to the boisterous minority in their constituents and never hearing the silent majority. We must never give up our rights in order to feel safe we must look to ourselves for our own safety because others will not always be available to protect us just like in San Bernardino and Orlando. When we give up all our rights we will then be at the mercy of a government and if that government is no longer benevolent we are doomed. Just watch the movie Red Dawn with Patrick Swayse and see what could happen. I know you will say it is only a movie and fiction but things that occurred in the beginning and throughout could happen and could also happen if our government became malevolent. If we cannot stand up to oppression we become nothing more than sheep.
