Shiranu, have you been to NYC? Have you experienced the culture there? I have and I'm with Nonsensei, it could have been literally anything.
If we were talking about a shooting of two muslims walking home from a mosque taking place in Columbus or St Louis or Kansas City then I would agree that there stands a good chance trump supporters were on the other end of the gun. But in NYC that chance is reduced to the point that its literally a nothing more than a dice roll. It could be their muslim background. But there is just as much a chance that it could be because they happened to be on that particular street at that particular time and nothing more.
