I don't know what their point was, but mine would be this: those 20-30 people a week shouldn't be allowed to keep their guns. I support their right to ownership and carry, but they really should lose that right (or at least that firearm and a substantial sum of money) if they're so careless as to forget that they have a lethal device stuffed in a bag that they've just packed for a flight. That kind of stupidity and negligence gives careful gun owners a bad name.

Ownership of a firearm requires a certain level of responsibility. A concealed carry permit increases that quotient of responsibility substantially. In my mind, forgetting where you put your gun is basically inexcusable. There may well be the odd, vanishingly unlikely circumstance where one could plausibly excuse unintentionally carrying a firearm through airport security, but I can't think of it.

My bet is that most of these idiots knew they had their guns with them but thought they'd try it on anyway, reasoning that if they went home to drop it off, they'd miss their flight.

I suppose that "far-fetched" isn't the right word to use, rather that it's absurd that that many people per week forget that they have a potentially loaded gun in their bag and are carrying it into a high-security area where they know they should specifically not have guns.

If we assume that those people don't have any malintent, then they're just careless. And if they are that careless, they should get their firearms confiscated from them and they should be fined.
