I don't want this to sound racist, but... 
Rather or not he targeted a certain ethnic group; the individuals who died, were Hispanic. What everybody is failing to realize about that fact, in my opinion is... 
Hispanic people tend to have family, more so than most "white" people. Hispanics have family near by to help each other, to bridge the gap when a love one is lost. From what I've seen in the news and Facebook posts, these victims, were loved and respected, by those around them. And the victims families seem to be there for one another. 
So... Not that any of this could be considered, a good thing. The fact that these victims left behind families that care enough about one another to support each other, is amazing. 
My deepest sympathy to these families.
