Then he should take a camel.
Your wife is not alone. Mine is middle-aged, matronly, sweet as can be and looks like the mixture of Scot-Irish, Italian and Cherokee which she is. She gets pulled over 9 in 10 times. One TSA worker even apologized and told her the day's quote of older white women hadn't been filled.!
IE, the day's "wasting of effort on people who wouldn't possibly be terrorists while letting people through who should be scrutinized better".
On our trips this past week to JFK from Oakland, my 86-year-old mom, in a wheelchair, was patted down on both trips. OK, I can see that an older lady may be vulnerable to someone sticking a device somewhere in the back of the wheelchair ... but in this case, she was being attended to by a JetBlue employee.
It was a very thorough search.
