I'm not defending anyone here and I believe there was prosecutorial overreach in this case, but I disagreed with the family's use of their son's obituary to make a political statement.
He was obviously a troubled man if he believed suicide was his only option. He needed assistance (and reading through his posts, it seems obvious in retrospect) and I think a better statement would have pushed for improved mental health awareness and assistance in the US.
Easy: they hired a "Social Business Development" executive who doesn't understand social media in the first place (i.e. when an internet mob is out, you ain't gonna stop it with one puny twitter account).
Also, we now know that they hired the husband of a well-connected US Attorney prosecutor with political ambitions. Of course they did it because of his qualifications, nobody is saying otherwise, but y'know, people talk and stuff.
