Regardless if it was intentional or not is irrelevant. In the Watch Dogs universe this Trayvonn Martin IS a drug dealing gangbanger who you can run over or shoot in the face. No relation to the real Trayvonn Martin. This is a different fictional Trayvonn who deals drugs, get over it bro. You don't see people with the same name as other drug dealers in the game QQing.
I'm not sure what I expected when I clicked this topic...
But this is the most hilariously stupid debate I've seen on this site in awhile. Let's just pull random similarities out of our ass and jump to some confounded conclusion that it was an intentional inclusion of a controversial subject in recent history.
Because, you know, every self respecting media publisher wants to put something controversial or potentially offensive in the background of their medium in such a way that it serves no sodding purpose to the storyline or gameplay itself, other than to cause potential flack later on.
