What's the problem with guns? They are nothing but an inanimate object...the same as your car, a baseball bat, your TV remote, a case of beer, etc.
Guns have a purpose and a place. They are a tool. In the hands of a skilled shooter, they can used to perform incredible displays of talent and skill in competition. They can be used to bring food to the table. They can be used to protect your life from something (or someone) wishing to do you harm.
But they can also be a dangerous thing when in the hand of the inexperienced or fool hearty. And so can your car, a baseball bat, that case of beer. And the list can go on.
If you don't like guns, that is, of course, your choice. If you are uncomfortable around them, its best to avoid them. But a gun, by itself, is nothing more then a paperweight.
In the hands of a responsbile gun owner/handler, a gun is a perfectly harmless object until the moment that deadly force is justifed. I carry a gun almost every time I leave my house, but being an LEO, that is not a shocking thing. It is loaded with a full magazine capacity and yes, one in the pipe...it is locked and loaded, ready for business if the need arises. But guess what, especially with my off duty/personal carry guns...about the only time leave the holster is when I clean them. If I don't need to have it out, I don't. But that doesn't mean that I'm not sitting with it on my hip in the car next to you at the traffic light, in the booth at the restaurant, at the movie theater, the local mall, any outdoor event I attend, etc. And you will never know I have it with me. That's called "being responsible." Not only am I handling the weapon responibly, but I am taking responsibility for my own safety. Not because I'm a LEO, but because I'm a citizen of the United States and its my Constitutional right to do so. I will not take action with my sidearm unless there is no other option. But it is not the gun taking that action...it is me.
If a pilot is approved to carry a firearm on the flight deck, as long as they are properly trained, I have no issue with it. In fact, I work with 3 airline pilots at my LEO job. I can assure you, they are ALL FFDOs.
The problem in this instance was that the pilot mishandled the weapon, in a manner we are not totally privy to, but clearly with an unsafe result. It was not the gun that was the problem...it was the person holding/handling it. And that boils down to whether the person was properly trained, properly skilled and had the right mindset to be in possession of that firearm.
I don't question their ability to safely and properly fly the airraft...but I do question their ability to safely handle a firearm.
