No actually it's as though you're saying "this guy violated a gun free zone; therefore all gun free zones are violated". Doesn't work.
No
They are saying that the guy and others like him, picked the place because it is posted as a gun free zone.
I understand that's what they're saying. And as I just said, that's complete speculation. Becuase we dare not blaspheme Almighty Gun.
Every mass shooting has occurred in a gun free zone. Do you think that is accidental?
