The Hi-Jackings of commercial airliners are occurring in part because we have made them too easy, and with little consequence to those who are intent on committing suicide anyway. It is possible to put back some negative consequences to those who are willing to die. The way to do that is to simply thwart their plans. Stop them before they can gain control of the plane and crash it into a building or fly it to Cuba (or wherever). If they can’t achieve their objectives, the glamour of suicide decreases.
The approach for doing that is simple:
1. Starting immediately, permit any flight crew member who is willing to go through some basic firearms training (I think about 40 hours would be sufficient) to carry a concealed weapon on board all flights.
2. We have lots of cops in this country who are authorized or required to carry firearms at all times. They usually carry concealed when off duty. I trust them. They also take trips, and I expect that most would prefer to be able to defend themselves, their families, and other innocent citizens when they travel. Immediately authorize any sworn peace officer to carry concealed weapons on any commercial flight.
3. Many law-abiding American citizens have voluntarily taken the required training and qualified for a concealed-weapons permit. Their record for responsible use of those firearms is even better than that of peace officers (although admittedly they don’t face as many challenges on the street as the peace officers). I trust them. Immediately permit any such licensed law-abiding American citizen to carry concealed weapons on any commercial flight.
4. There are empty seats on most commercial flights. Likewise, there are many law-abiding American citizens who would like to take trips on commercial airline flights, but can’t afford as many trips as they would like. Permit any such law-abiding American citizen (for a first definition, any off-duty peace officer or holder of a CCW permit) to fly on a “space-available” basis at low cost or no cost, so long as they agree to bring their concealed weapon.
5. As a last resort, or perhaps as a temporary measure, return the armed Sky Marshals until the other citizens described above can fill the need.
