Yeah, you're right. It's easy to get lost in the crowd. Of course, it's another thing for a person to snap and cause this kind of horror. No sane person would ever consider doing such a thing and I'm sure the guy had huge issues.

It's a sad sad thing, but to be honest I don't think there's really a way to prevent such things, except maybe give the guy the care he needs. But it's unlikely people really have noticed in such a way that they would be alarmed enough to take action.

I think the killings in Gaza are totally comparable when it comes to how pointless and horrific both are, "war" zone or not.
