We should be wondering why such attacks take place.
I've no idea why that particular lad did what he did, I've not followed it that closely. But like many terrorist attacks, if that is what it was, generally it will be because we've attacked people of another country. Whether that be Syria, Libya, wherever, after some of the documentaries I've seen, I would want to seek revenge to. I hasten to add, that's not meant to justify what that lad did, it's just to say that the world is a very sick place.
