Before you watch this video again or another one like it I'd like you to think hard about how the victims' relatives feel about this video existing. Peace be with you.
It does not belong on YouTube, but absolutely belongs in some sort of publicly accessible archive behind the digital wall of possibly a free signup form and definitely some reminders of just what you’re about to look at. And before anyone suggests some variation of right to be forgotten, I’d counter-argue that right ends when what happens to you is a national tragedy that significantly changes the society you lived in.
