I think we need to stop thinking about guns as zero sum. I have one and have no problem with concealed carry. My points still stand in my previous post that 3 wannabe heros in a crowded airport are far more dangerous to the public than additional police.
The argument was mad that an airport is a gun free zone and thus an ideal target for mass shootings. On the contrary, there is more armed presence in an airport than most public places on the planet.
