There is a flip side to the coin.
If the US banned guns they would be giving up, they would be giving up an enshrined right that has been upheld since 1791.
Imagine if the Canadian government took away out right to improper search and seizure, using the argument that innocent people have nothing to hide so only the guilty will suffer.
Would we stand for that? It would make the police's job easier and give them a created ability to control and curb crime.
How can a sane and logical society put such an impediment on law enforcement for the safety of the citizens?
I for one would not want to give up that right. I don't do anything wrong, yet I don't need the police to be going through my things if they desire.
Just like a US citizen feels like they shouldn't have to give up their gun because someone else abused their right.
You lose your rights by abusing them, not because others do.
As a Canadian who grew up only ever seeing a gun on the hip of a police officer, I can't say I'm against gun control as I believe in it.
But the more I think of it the more I think gun control is less about guns per say, and about an explicit right being removed because of a (assumingly) small percentage of the population abusing the right.
You wouldn't remove Free Speech because a fraction of the population abused it with hate speech, nor would you remove the right to improper search because getting a warrant is a hassle and could be time consuming.
For me the question is where does the line be drawn?
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
We need to define Militia, is the right to keep and bear arms dependant on being part of a militia? What people? The ones the drafters were referring to or who we consider people today? What was meant by arms? Could someone in 1791 own cannons? What is the intention of the meaning of arms?
Then again, does arms have to mean fire arms? Could it be a method of defence?
I'm no expert of the US constitution.
I honestly don't think repealing the second amendment is the answer.
I think there are major problems with the US constitution, but I don't know if removing rights is the way to go. Clarifying what a right to keep and bear arms actually means would go a long way.
Additionally if the US was to implement a registry I think the best way would be to grandfather it in.
Once manufactured they are registered. Then the gun is tracked (like a shipping label) to the retailer, who then tracks the owner. Any change of ownership happens the gun must be registered (just like land transactions).
When a gun is used in a crime, it would trigger the search of the residence of the gun owner (unless reported stolen) and the possessor. Any additional guns found in the home are registered.
Anyone convicted of a crime must register all guns.
Retailers would have to keep records of stock (not just quantity but series numbers) and keep the registry up to date.
