It's a sad state of affairs when the federal government takes people who either don't realize, after nearly two weeks, that the very expensive pen they unintentionally took home from work is not their pen, or who realize it isn't their pen but don't think that they should try and return it to the owner or a lost and found. That speaks volumes about the quality of the TSA workforce.
On the other hand, the story may be that he is a common thief. That speaks volumes about the TSA workforce as well.
Either way, the most dangerous part travelling on a commercial airline is transiting the TSA checkpoint. That' when the risk of arrest is highest, the risk of fines is highest, the risk of unwanted touching is highest, the risk of verbal abuse is highest, and the risk of theft is highest. Additionally, there's health risks to consider.
This continuing story is just a reminder that the TSA poses the greatest risk to the airline passenger.
