The NRA ignores the wishes of it's own members who overwhelmingly support things like detailed background checks and keeping guns out of the hands of mentally ill people.
None of which would have stopped Paddock, but let's not allow reality to get in the way of your feelings.
Feelings rule you. What is it with people that find some anecdotal thing that supports what they believe and they immediately extrapolate it out into infinity. "Well if this one thing happened then all things happen". Reality doesn't work like that. "Well we have laws against stealing but one person still stole something so no laws against stealing work".
By this reasoning no laws are of any value so why have them.
An Ad Absurdum argument that is ridiculous. All of human existence is about minimizing damage. Many people that wear seatbelts die in car crashes. We still require seatbelts because they save many lives. People die running red lights and stop signs, nobody then argues red lights and stop signs should be done away with because in one instance or even a thousand people ignored the law or such devices were less than 100% effective.
To argue such a thing is the realm of the lazy, those people that have no real grasp on something but find one instance of an exception and then apply it across the board in all circumstances. Real life is far messier and muddier than that but the lazy look for the easiest path that requires the least amount of thought.
