There have been multiple reported cases of theft by screeners at DEN. Those are facts. The reports seem to be a little less frequent now, and it appears that the offenders are being fired and dealt with. But I'd still be careful everywhere and a little more so at DEN.

And it matters not to passengers if WTMDs are set differently or if they are all set the same but the dielectric and metal environments around the WTMDs cause them to behave differently. What matters to passengers is if they set off the WTMD while carrying their usual complement of clothes and metal, and based on passenger reports here, there is inconsistency at DEN and elsewhere.

I'm not sure what rational reason TSA has for being so secretive about WTMD settings. Anyone who flys a lot or even anyone who peruses FT posts from early 2001 to present can get a reasonable approximation as to when major (national) changes in sensitivity happened and when large-scale equipment replacements happened.
