That’s the whole point: not knowing.
The criminals are afraid when they don’t know who is armed.
That’s why it works as a deterrent.
And that is why “gun free zones” are idiotic.
I feel bad for those hapless, well meaning but (what is a good non insulting word?) fools that put signs in front of their homes advertising that they don’t have guns, or that they oppose gun ownership... and see them take the signs down two or three weeks after, after they had been the subject of a few robberies.
I just know What we need,
A bullet proof
“Gun Free Zone”
Sign!
In case of gun violence
place sign on gun and
go to You’re Safe Space.
