In this corner, you have the idea that everything should be searched, because the terrorists could be using that lady in a wheelchair unbeknownst to her, or perhaps holding a family member hostage. No exceptions.
In the other corner, you have the idea that profiling should be done, so you're looking for names on a no-fly list, sweating, and strange or alien people--selective enforcement.
In another corner, you have a weird hybrid where you try to take a hard line with people of a certain age, gaining none of the advantages and all the disadvantages of the first two approaches, plus you give Alex Jones something to talk about on national TV.
I still say, hold a cocktail party for half an hour at the gate, and if you don't feel comfortable with your fellow passengers, take a later flight. Bring your own weapons, if you want. Statistically, it would still be safer than driving.
