Laptop bag--they unpacked every bit of electronics in it. Nobody's ever done that before.

They also pulled my camera bag out of the bag it was in and ran both through separately, again something nobody has done before.

Finally, I had the flight-legal Letherman tool--they declared it a "small knife", it wouldn't fly. At least it didn't take long to mail it (we have relatives over there, I'll get it next time.)

(And their luggage x-ray caught a power bank I inadvertently packed but that was legitimately my oops.)

I would say they were poking around in at least 1 in 3 bags.
