Shotguns are not allowed through airport security. But what does that matter if you can build one from items purchased in an airport gift shop? The break-action shotgun pictured above was made from Red Bull cans, a hair dryer, batteries and a can of Axe body spray – and it can blast a handful of pocket change through a sheet of drywall.
My dad always says that if someone wants to hurt you bad enough, they'll find a way to do it. However, it looks like they don't even have to try that hard. All they have to do is get a little clever. To me, knowing that this is possible is NOT scary. This has been possible for years and will go one being possible. Why am I not afraid? Simple: the overwhelming majority of people on Earth are not killers, terrorists or psychopaths. The overwhelming majority of people in airports are just trying to travel, just like you. And if you happen to have the bad luck of ending up on a plane or in a terminal at the same time as a killer, terrorist or a psychopath, take stock in knowing that it was just random bad luck.
Or, if you swung by Evan Booth's website, you may have already learned how to arm yourself against the insanely unlikely event of being on a plane or in a terminal at the same time as a mean person. That's ultimately my point. All these security measures at airports (taking off our shoes, x-raying our bags/coats/laptops etc, backscatter x-raying our bodies and sometimes getting felt up by a TSA agent) are not going to stop someone who really wants to hurt people.
The likelihood of getting hit by a car, even killed by one, is infinitely higher than of getting killed, or even harmed, in an air-travel-related act of violence. But do we ban cars, stop ourselves from crossing the street, or avoid leaving our homes? Of course not. Yet we act like we can stop someone if they really want to be horrible at the airport.
But the odds are in our favor. So, why bother living in fear? Why bother making air travel such a huge pain in the ass? Sure, keep x-raying bags and making me empty my pockets, but can I please keep my shoes on and my water bottle filled?
