We humans have some peculiar traits—but blaming the messenger has to be one of the strangest. The cops are alerting the public to what is a public safety issue and asking the folks to at least safeguard their firearms. Burglars and thieves love the gun owners that believe their responsibility to secure their weapon(s) stops by locking the doors. My guns are secure only in my locked gun safe or on my person; otherwise, they're only safeguarded.
I agree with you but the thing is we should lock our guns up because we are smart gun owners not because they tell me I have to. My wife and I are empty nesters. Now if I left all of my guns out IMHO I would be negligent. I lock them up and they are tucked safely in to my gun safe and 90% of my ammo is stacked up in a second. But if I want to leave a AR out over night leaning in the corner then I should be able to.
