First, before you make statements like that, you need to understand the motivation of the people doing this.
And since we have no idea who did what, where, why and how, its far to early to judge if it made any sense or not.
That is not to say that I condone senseless violence. However to prevent further incidents you must understand the motivations of the perpetrators and understand from their world view. Just saying they are evil isn't going to help you understand why they did it.
After all if you don't understand how desperate they are, you don't know to what level they will stoop.
