You'd cry hypocrite when names haven't been released and lord only knows who's involved? How would you like to take part in jokes about some lady being beaten then find out it was your mother? I have a son who could be on that bus (if he didn't detest busses and like to fly) We can laugh at anything - but it's not jokeworthy when it's close to home.
I'd laugh just the same. I disagree and find it more reprehensible that you think its not jokeworthy unless they are foreigners (either literally another country or far away in a community sense).
"Close to home" doesn't cut it with me, im not less attached to someone in another country than I am another province or even another town.
Hell, I have laughed at family tragedy and still think some of the jokes were good ones.
