That’s exactly what they’re doing with the firearms owners.
How do you know? Do you know that they refused to canvass? Do you know that they didn't interview the victims’ families? Did you know that the cops didn't visit their schools to see if there were any issues? Past reports of threats or acts of violence?
Tell me you have knowledge that these actions were not taken.
