Greywolf had already established it was a knife, not a pistol, before leaving his house. Your hypothetical is an irrelevant attempt to justify a losing argument.
I doubt anyone here would have left the house, had the old man been wielding a sidearm. But he wasn't.
I'm not justifying a losing argument.
There's not a shred of doubt that the SMART thing to do was stay inside the house.
You stated that you doubt that anyone would have went out if the old man had a firearm....
Which leads to the point I made earlier in this thread:
Greywolf went out in to a situation that he knew nothing about.
Sure he saw a knife in the old man's hands, but he didn't know if the old man had a pistol in his waistband or pocket.
If you look out a window and see what APPEARS to be an unarmed person, does not mean that they are in fact unarmed?
Of course not!
They might have a handgun.
How many of us, here on this forum, APPEAR unarmed while doing out daily activities?
Why take such a foolish risk when there was no urgency to the situation whatsoever?
Trying to justify venturing out to confront a hostile person is the real losing argument.
