I love the fact that someone thinks a baggage handler would get away with stealing a massive 27" computer without getting caught....
That's because the Postal Inspector's who go after theft on the airlines with more vigor than the airlines let theft go on a long time before moving in. And generally the mail doesn't have people pawing through your stuff like airline security, who is allowed into your bags if you fly.
Basically, if they get caught it'll be in 6-18 months and your stuff will be long gone.
