What do you call a picture of the Boston bombing? A photo bombing
The victims of the bombings in Boston you are referring to? How could you be disrespectful like this with your verbal comments?
I only joke. I don't care about the victims, what happened was meaningless.
You shouldn't be so insensitive when it comes to violence behavior against innocent people, what would you feel if you were one of the victim's families? Take an approach that is more serious and caring when it comes to such happenings, and joke about other things in a lighter manner. It's the overall quality and not the rudeness that counts in humor.
