I think I might have respected that response to the first post.
Calling them nothing seems a bit insensitive.
Well, let's be honest, it is nothing.
It isn't that they (the murdered) don't matter. It isn't that this isn't a tragic story.
It is that pointing to one, worst case, issue and linking it to the President rather than the myriad of other factors you could link it to (upbringing, drug war, educational level, prison institutionalization, etc.) you simply link it to the thing you don't like. In other words, the relation level to the President is...nothing (or negligible at best).
Let's all recognize that nobody is saying that these murders aren't horrible...tragic. We all realize that the victims and their families deserve the utmost condolences. However, any reasonable person also realizes that their murder can be directly linked to...their murderer...not the leader of the nation that happens to be in office when this guy commits said murder.
