Do you mean due diligence like emptying the lighters before packing them? Why would an airline still want to confiscate empty lighters from checked baggage stowed in an inaccessible part of the plane? What more was he supposed to do?

The airline's rules, clearly stated on their web site, say nothing about them being empty or full. The rules say not to pack them, period. I can't see how it could be more clear. Don't take them at all, risk them being confiscated with the attendant hassle, or take another mode of transportation.

Because they simply don't have time to check every possible source of ignition in checked baggage for the presence of flammable gas? It takes long enough to endure the stylized rectal examination that is flying today.
What more was he supposed to do?
Ask the airline before packing them would seem to be the right answer to me. If then told that they would not be allowed, he could have left his "old friends" home then gone to the airport gift shop and bought a Bic with an adjustable flame that members of the common herd like me uses every day to light cigars.
I just don't see any cause for outrage here. The guy failed to follow the rules and paid for it. If he doesn't like it, let him do the due diligence next time or take the bus.
