The training has the TSA TDCs asking the child for the child's name, asking the child who is the person accompanying them, and asking the child if the child knows where they are going and can tell them the place to where they are headed.

If you witness all of the above at the TDC, then you should know what the TDC thinks of the passengers.

The TSA engages in an obnoxious approach at heart by asking questions of the child while acting as if the accompanying parent/guardian/in loco parentis isn't there and/or is a criminal child trafficker.
