Is Terrorism Funny?

What would you do if, walking by Ground Zero, you saw people pretending to be 9/11 terrorists posing for photos? That’s pretty much that same thing that’s happening in Times Square according to the New York Times, albeit in reference the more recent bombing of an Army recruiting station:

“Jokesters posed for pictures while pulling hoodies over their heads and making handlebar gestures — an allusion to the suspected bomber who surveillance footage indicated wore a hooded sweatshirt or jacket and rode a bicycle.”

Nobody died in the Times Square bombing. Does that give us license to ridicule it?
