First, let me say that I enthuastically support pilots being able to carry a (real) gun in my flight bag. I hope my airline doesn't wimp out on this issue.
There has been some discussion on this in a previous thread "United pilots to carry taser guns."
I am sure thee will be lots of (non-crewmembers) who will bemoan this possibility. But I think it is a great idea. I just hope they don't make it prohibitively difficult to be individually authorized. The head of ALPA said on TV he thought a pilot shoud take a TWO WEEK training course at a MILITARY FACILITY to become qualified.
Nonsense.
That's my story and I'm stickin to it.
