I don't know the answer to gun violence, I wish I did. But stopping people from legally owning them isn't going to stop people getting them, especially in a country the size of the USA and especially considering just how many legal guns already exist in the first place not to mention god knows how many illegal firearms already in the pool. We can't just expect all legal gun owners to willingly hand over their guns, and then what do you do? Go after them all with force? Either way it misses the real issue and that seems to be in most cases the mental state of the shooter and the lack of medical help that is available to them. But even then, people can just flip like a switch with no prior warning signs. Basically if someones out to kill someone they will always find a way.
I live in the UK and we haven't had easy access to guns for nearly 100 years. But we still managed to have a School massacre, and there are gun deaths regularly in the UK, not as often as the US but look at the size of the population difference and how few guns there are here to begin with. Banning gun ownership just meant the bad guys got to keep them whilst we were left defenceless, you really don't want to end up like the UK in that regard.
If gun ownership was banned in the US it would likely take 100 years or more to get to the point we're at in the UK, and you still won't have totally eliminated.
You should cherish the 2A and the Bill of Rights, certainly not want to erode them. That's what happened to us and living in the UK feels more Orwellian by the day. The people have no power to oppose a tyrannical government, the population has been disarmed all the while the civil police force has been armed more and more each year be it firearms and Tasers. Politicians love to use tragedies to push their agenda which I think is a disgrace. Innocent people have died today and their lives shouldn't be used as a plaything in a tug of war over political issues.
We have to learn from history, not make the same mistakes, giving up more and more of our civil liberties will only end one way. I look to America as the last bastion of hope in this world, especially as a citizen of a country that arrests and imprisons people for speaking their mind.
