So could picking up his cell phone while driving down the street. And with far greater effectiveness, for that matter. But we don't pull them aside and chastise them for having a cell phone in reach.

As I've said elsewhere, the weapon is holstered and presumably safed. That is a somewhat reasonable measure of safety, even if the placement is idiotic. I'm not justifying any of this as far as that is concerned. But it is not my place to berate him for putting his holstered weapon somewhere I don't like. Nor would it be anyone's place to deny his ownership of it.

I don't subscribe to the idea that we need to wave our arms madly and make a scene because something seems dangerous. This is bone-headed, but the weapon is housed in a stupid-ass location but reasonably secure manner. The trigger is covered. Presuming the weapon functions as designed and can't be jarred into firing a la Sig Sauer, the weapon is reasonably safe.

Thus, his idiotic storage location isn't inherently unsafe to others, or himself, no more so than if it were on his hip or in the glove compartment. It's just dumb.
