What is your opinion on the Second Amendment?

Citizens DO have the right to own firearms. That said, there are those who for a number of reasons should not have access to firearms, such as mental illness, domestic violence, history of violence/confrontations with law enforcement, to name a few. One glaring omission is the criminal element in the US who have weapons (mostly illegal)(guns). They're not too high on the authorities' lists to be gone after and have those firearms taken from them.

I think your second part would be dependent on who(political party) at the time is the "Government".

You may be aware, but if not here's a related article. And for all those countries claiming they're gun violence is unlike America's, well there are like minded people in those counties who too, don't want the Gov't taking their guns from them. It's not unique to America. https://americanmilitarynews.com/2019/07/less-than-1-participate-in-new-zealand-gun-buyback/
