The problem here is, you're actually furthering the Bloomberg narrative. You're taking an event so incredibly unlikely that it makes winning the lottery look commonplace, and you're screaming "THIS COULD HAPPEN TO YOU!!!!!!"
Now, some people will react to that by wanting to be armed. But most people will be made more open to the notion of gun control and "Something needs to be done!"
