Situational awareness is about more than just one's access to a firearm.
I agree, and I covered that.
What I see are people pointing that out, not saying to treat it like "quiet time".
Someone else said:
The gun in my pocket would not have even come to mind.
I don't think that wise. Again, if something is developing, assessing options is wise. Just because you have a pistol in your pocket doesn't mean it is your only option, but it is certainly one option among many, and I wouldn't completely rule out the possibility of it being needed. I am anything but trigger-happy, but carrying a pistol and then figuratively forgetting it is there when assessing my options in a situation like that is not the way I would play it.
