Boston asshole tries to find the humor in mass death

Considering people (and many children) were blown up at the concert.

And it really has nothing to do with freedom of speech. (oh, BTW, there are limits on that also. Ya know, defamation of character, that sort of thing that folks go to court over?)

congrats you literally don't know what "black comedy humor" is

i will say that i privately made my own jokes to an audience i knew would take them for what they were. somebody showed me a video of the concert hall (you saw no explosions/bodies or anything of that nature) and i heard the big pop and then of course the confusion that followed. it pretty effectively made me lose interest in making jokes about it, but if somebody else can be funny with it i encourage them to go wild.

Here, let the country where this occurred tell you exactly why it may not be your cup of tea, but it's good for our psyche to hear black comedy:

Any fan of Peter Cook or Bill Hicks will attest that dark humour predated the internet, however, and none other than Sigmund Freud addressed the topic in his 1927 essay Humour (Der Humor).
In it, the father of psychoanalysis argued that sick jokes were the mechanism by which the ego "insists that it cannot be affected by the traumas of the external world".
His analysis is shared by Dr Oliver Double, an expert in comedy at the University of Kent who believes that tackling offensive subjects can be a very effective tool of satire as well as a form of therapy.
For instance, Dr Double was in the audience for Connolly's Ken Bigley routine and argues it was a carefully-argued attack on media prurience rather than the opportunistic swipe at a family's tragedy it was portrayed as in the press.

The problem here is that this guy's attempt wasn't a good one. It relies too heavily on making fun of the victims. It begins with a news headline about the dead rather than an assumption that you already know that there are victims of the bombing. It's just poorly constructed.

Maybe a better black comedy joke would have been: I hear that the bomber waited until the end of the concert because the ticket was so expensive he couldn't let it go to waste.
