Baggage handlers are the same all over the world. Poorly paid, physically exhausting and back breaking work with very little job satisfaction. How do you know your bags weren't ransacked at the other end?
I work at POP airport. Been here for 7 years. I've never seen handlers going through luggage here. Not to say it doesn't happen, but your bags are always under the eyes of someone. Not only is there the IATA required security scan, they are also screened for narcotics too. So you have security, customs and drugs officials screening your bags before they are escorted to the aircraft. Unless they are all in it together, they wouldn't hesitate to grass someone up if they caught someone with their hands in a bag. Most wouldn't risk what could be considered as a decent job, just to get their hands on a hairdryer or an electric razor.
However, the security personnel at so called civilised countries have TSA keys and are allowed to enter any bag that may cause suspicion without the owner's consent. See a bag with a laptop inside with your xray machine on a bag labelled to go to the DR. Open it up, nick the laptop and blame the POOR thieves in the poor country!
And if you're dumb enough to pack anything valuable in your checked suitcase, you deserve to get it nicked!
