Did you hear about those Vegas Shootings? It got me thinking, concerts should stop having open bars, people take too many shots!
Are you making fun of victims in mass shootings? How disturbing to think about it in this way.
It's just a joke. I could never hurt anyone.
I'm not very pleased about the trivialization of your comment, it seems to be something of a callous nature. Refrain from being that insensitive, it could cause a survivor or relative of the deceased to have distressing feelings. Be more adult and joke about lighter things which are much more hilarious.
