Potentially, but that implies leaving guns around outside of safes around kids isn’t all that dangerous considering the high number of gun owner and guns.
I don’t believe that’s the case. I think it is more likely a few idiots cause a majority of the pain and loss of life.
I have no data on this but anecdotally I can honestly say I despite being around idiots and gun owners in rural country with my now trump loving mother, that I have not met 1 single person even remotely close to dumb enough to leave a 2 year old in a car in the summer of GA, unbuckled and free to roam the car, that has a unlocked loaded gun.
I understand the challenge with using personal experience, but in the absence of any real data, this is what I have to work with.
