Regarding thefts by luggage handlers, yes, they have been caught and charges were filed. However, our city attorney would only file misdeamenor charges if they have no criminal history, even if the value of the stolen goods placed them in a felony level. Therefore, they are out the next day working for another baggage company. (Many airlines contract out baggage operation and these companies can't share employee's record due to some privacy issue) But thefts occurr so much down in the ramps, officers are only catching less than 10% of these thieves due to lack of resources.
Thefts by TSA is harder to catch and prosecute due to their federal employee status. They get terminated but no one knows if any charges were filed. Feds aren't proud of these employees so the public rarely hears about TSA theives.
Fortunately, luggage thefts have declined since TSA took over private security companies. But for a victim who lost his/her valuable, that's one theft too many.
One important fact I would like to point out...most items stolen were electronics, such as laptops, digital cameras, iPods, jewerly, etc. I guess thieves don't scuba dive :no
