ya know- not being a lawyer, but having re-read the regulations- it looks like it comes down to 'what the meaing' of "retain" is.
And except for combination locks (where the combo could be retained in the person's memory), I can't see how temporarily handing them the key to the case is anything but temporary retention.
I think they'd have a very difficult time prosecuting anyone for doing what the TSA told them to do wrt to the keys to the cases...
Unless you'd just prefer no one touch your stuff, which I understand.
