Yeah, this is really sad, but not a surprise. This terrorist attack has illustrated what "decolonization" is really all about--killing the so-called "colonizer" regardless of who they are, man, woman, child, and whether or not the person is sympathetic to your cause. Aside from those publically celebrating this, I'm sure there are many more who approve of what happened in Israel. Imagine something like this happening in Canada. What can the police do? We have almost no military. And how convenient that gun-ownership has become so restricted. Don't be surprized if something like this happens in some parts of Canada within the next decade or so.
