"have you stopped beating your wife yet?"
That is a logical fallacy known as the Complex Question. One need merely identify the premise (being a wife-beater), and then reject it.
However, the OP was not in fact, a logical fallacy. It simply asks if one knows another not to be trusted with firearms... 
Or, if I'm missing something, what is the precise and relevant premise of the question you reject?
Not sure you're not one of 'm 
When my twins were two months old, there was brief moment when I was ready to KILL my husband when he let the dogs wake up the babies. (I was *very* sleep deprived). I was completely convinced I would explain this to a jury, and they would applaud me, because, HELLO! SLEEPING BABIES!!!
Then I got a nap. Life was better after the nap.
No guns in my house - lol!
I love my husband. 
For one shining moment, I *knew* killing him was the right thing to do. Seriously, HE LET THE DOGS WAKE UP THE BABIES.
In my defense, I was on two months of non-existent sleep, and that particular night had gotten 45 minutes total in three separate sequences (20 mins, 10 mins, 15 mins). My beloved was trying to be quiet so all of us could "sleep" which was why he hadn't let the dogs out, but within five minutes of leaving the house, the dogs began barking so they could have their morning constitutional, which set off the babies, one of whom was on oxygen and a heart monitor, which began screeching, while the cat was leaping near the glass of warm water right by the computer --
Did I mention it was a rough moment? Once I got everybody/everything under control, I called and explained to him that I was going to KILL HIM IN HIS SLEEP if he *ever* did that again (he was very confused), at which point he gently told me it was time to call my mom for some relief, and I started crying. My mother promptly came over, I got two hours of blissful uninterrupted sleep, and then he gently told me I had really hurt his feelings by threatening to kill him. I apologized, and we began working on ways for me to get at least four hours of sleep a day (twins!).
But there was a moment, and I will never forget it, where I really meant it, and I wasn't worried about a jury convicting me because I *knew* they would understand his "horrible crime."
I know - 
right?
Looking back, I had officially entered into temporary 
land.
He is a good man. The twins are six now. No guns in our house! 
He didn't discuss it with his family first. It was very sad. 
and we're not in Iowa.
... from her home (she was a hoarder and a danger to herself and others.) I'm certain the police would have shot her to death.
My parents thought they had all her guns but later found more in the mess.
Instead my grandma got to live long enough to enjoy the weddings of a few grandkids.
But I've also got a few horrible stories about people who shouldn't have had guns.
I don't think ANYONE with a gun fetish should have a gun.
One of my siblings has a few of the family guns, but nobody has bought a gun since my grandparents' generation.
I had four great-grandmas who were powerful women of the wild west. They could all hunt.
My mom did not allow guns in her house. No exceptions. Our family tends to be a matriarchy. If one of the matriarchs sees a gun being used in an irresponsible manner that gun is gone for good. I've seen my mom take guns away from people and break them.
We don't allow guns in our home either, especially in our neighborhood where guns are usually what burglars are looking for when they break into homes. They don't want your consumer crap, they can buy that themselves. They want guns and ammunition and have been known to take entire gun safes.
If I can see it, it is factored into my decision making and future actions. I think that is a rational response to being in the presence of a deadly device. I'm also cautious around people with chain saws.
