Should More Gun Control Laws Be Enacted?
“[Moderator Maria Bartiromo] Mr. Trump, are there any circumstances that you think we should be limiting gun sales of any kind in America?
TRUMP: No. I am a 2nd amendment person. If we had guns in California on the other side where the bullets went in the different direction, you wouldn’t have 14 or 15 people dead right now.
If even in Paris, if they had guns on the other side, going in the opposite direction, you wouldn’t have 130 people plus dead. So the answer is no ”
That was in 2016.
