If the media reported on every single terrorist incident then we'd hear about nothing else. There are practically daily attacks in areas where it's expected daily so sadly isn't really "news" anymore. This incident was more ferocious than usual hence why we're hearing about it.

The reason people go crazier if it happens closer to home is because it's not only more newsworthy to them but also because it's not expected to happen around here. I understand why the media and people react more when it happens here but I'd also encourage them to acknowledge that it happens a lot in other parts of the world, hence why I've never changed my avatar to a French or Belgian or German flag. That gets tiresome really quickly.
