To the leftwing I would say: Freedom isn't safe, there's always risk in freedom. You have to accept some aspects of risk and danger with freedom.
To the rightwing I would say: Tyranny and shooting people isn't a freedom, so stop selling guns to crazy people. If you can take away a felon's God-given right to vote as a citizen, then you can not sell guns to every nutcase who wants one. And if you think YOU are the nutcase they won't sell to. Maybe you shouldn't own a gun.
@quinnsentialOne agree. States with stricter laws and training requirements have better outcomes.
