So far there's been very little pre-check-in screening in Western Europe - see Brussels, for example. I'd expect that to change but I can't imagine the nightmare it will cause if they add another level of screening at Heathrow or de Gaulle .
The rest of the world is all over the map, so to speak. In my experience India and a lot of Southeast Asia pre-screen luggage, as do parts of South America, but it's not consistent. In some cases they seem more concerned about agricultural products than anything.

It doesn’t matter how much screening they do when they hire muslims to do the screening.
