Not being funny but this is massively unfunny, that wreath was for the Boston bomb victims.
I'd be with you if you were right, but that wreath wasn't for the Boston Bomb victims, it was for shameless and disgusting self promotion of Liverpool football club.
Liverpool tour 2014 is written on it.
The whole photo shopping thing is to highlight how wrong they were, and how their tour of the Boston Bombing site, the 911 memorial and whatever terrible disaster they want to visit next, and whatever disgrace they care to bring on themselves whilst there, by taking the opportunity to pop up grinning, holding Liverpool shirts and pretending to mourn, is so terribly wrong.
They are disgraceful in their behaviour, and whilst the pictures are in bad taste, this is just a parody of their lack of humility and good grace in the light of terrible tragedy, the joke is not against the victims, but ironically against Liverpool who are of course normally always the victims, except in this case when they are going out of there way to insult actual victims by callously trying to sell their brand on the back of tragic circumstances.
