I'm in my 50's and I've never owned a gun either. I entirely support gun control - to an extent that would possibly make even some other gun control advocates uncomfortable. My voting history has me being so blue that you'd swear I ate the wrong gum at Willy Wonka's chocolate factory.
My first post that you reacted to was not about predicting the behavior of the shooter, it was about the sheriff disingenuously saying that there were just no signs that anything was going to happen. There objectively were signs. You aren't an 18 year old, I assume. Actions that you do as an adult would be viewed different than the same actions done by a teenager. An 18 year old buying two semi-automatic rifles should raise concern, whether it's a legal activity or not, and I would even argue that the shop that sold them should have been on alert that something unusual happened and consider reporting even that. Just like someone buying all of the ingredients to make a bomb should raise concern, even if each element is legal to buy. But my post was about the sheriff.
That sheriff wants to absolve himself of any responsibility, when in my opinion, he is very much entwined in it. He, or you, or anyone, could argue that it's the state that allows such gun purchases so there's nothing he can do, but if he is voting and continuing that cabal to be in power, then he is part of the problem. I can predict that he will continue to vote the same way, because he does have a history of it, and he should be called out for shirking his responsibility in this situation of uncontrolled gun violence.
We can try to solve more than one problem at a time. If gun control could be passed tomorrow, great, but I also feel these repubs in office around the state need to start being held accountable for their actions.
