I've heard that this happens frequently with the TSA in the United States and almost always in checked-in bags. I'll be travelling soon to Los Angeles for a holiday and I don't know whether to be alert or not.
I remember once leaving an expensive laptop in a checked-in bag from NBO to DUB through ADD and if my bags could transit through countries that pay workers very little without anything being stolen, then it should reason that I'm safe if I put one or two electronics in my suitcases that will be checked in from DUB to LAX?
Am I mistaken or not?
