I agree

that some parents are to blame for firearm accidents or shootings with minors. If a 2 year old grabs dad’s loaded pistol from the kitchen counter or from between the seats of the car, yes the parent is to blame. If a parent actively tries to cover up evidence of a firearm crime the child committed like in the Michigan school shooting a few months ago, throw the book at them and flush the jail key down the toilet. But when I was 16 I knew damn well that firearms were not out of the safe unless we were shooting with a responsible adult, I knew damn well that firearms, even unloaded, were not pointed at another person, I knew damn well that actions with a firearm were life or death. Why did I know this? Because it started at home when I was 3 or 4 and continued in 7th grade when we were required to take hunters safety in pe class.
When I was 16 I also knew how to get in the gun safe on my own and I was occasionally left alone and I often did stupid shit, but not with a firearm because I knew that it was life or death.
Is it fair to blame parents if for all we know they have done everything in their control to keep weapons away from their kids? Time will tell, but blaming all parents for gun accidents or shootings is painting with a broad brush.
Show me an example where having hunter/firearm education has led to more accidents.
According to this article from the Dallas news.com hunters safety was not required in Texas until 1988. At that time it was required anyone born after Sept 2 1971 must pass hunters safety to possess a firearm. In 1966 Texas PWD began tracking firearm accidents. There 85 that year with 28 fatal. Three decades later 56,000 Texans a year pass hunters Ed. There were 21 firearm accidents in 2017. This is still to many firearms accidents, but hunters education helps. It has been proven over and over.
