Hi,
what would be a good way to check for events globally (if any)

What I'm trying to do is if the player loots a human character I want to know that he is looting and possibly what he is looting.

Now I could possibly do that by assigning a script to every base actor checking for OnUnequip etc. but is there a nicer way?

At least tell me it cannot be done, so I can stop trying to figure it out

Look into Story Manager event nodes. That's exactly what you're after. Specificallyhttp://www.creationkit.com/Player_Add_Item with Acquire Type 6
