Hey girl is your name Sandy? because I want to shoot some kids inside you.also you look like a Hooker. i know what the ladies like to hear B)
This joke is poorly executed, why do you want to offend school shooting victims?
It's funny to make jokes out of traumatic experiences, to see others reactions.
Making a joke about a school shooting is in poor taste. If you verbalize such jokes to people, they may see you as being insensitive and mentally disturbed. Certain doors may be closed to you as a result.
