I did some googling for the urine thread earlier today and ran across some very disturbing things.
There is a link to a college forum where someone reports a radio program earlier this week. An elderly woman wearing an incontinence pad was forced to remove it in public to prove the contents to screeners. Her lawyer was on the radio show.
Then I stumbled onto what I believe was a fetish forum for people who wear diapers. There were reports of their diaper cream being taken away as well as diapers.
No matter what ones personal opinion about that fetish, a TSO has no reason to take away items which are listed as medically required or to make a judgement on whether or not someone 'needs' the items.
