My opinion is simply that gun laws would never stop something like this. There is a law against murder too. I’m sure that is very reassuring to the families of the 33 people who have died.
I think it is false and disingenuous of both sides to use this horrible event to prove their point. This event has nothing to add to the gun control argument. Insane, evil people do insane, evil things no matter what law is on the book.
