Let's
say that somebody notices that I am armed and calls the cops. In
fact,
let's HOPE that somebody notices that I'm armed and calls the cops.
That's
certainly what I would do if I saw someone who was carrying a gun on
the
flight line.

Why in the world would you call the cops?

Because, like what I hope is the majority of sensible pilots, I actively
participate in AOPA's Airport Watch program. A quick reading of any
material from Airport Watch (http://www.aopa.org/asn/watch.html) will tell
you that we are meant to be looking out for anything that we think is
"suspicious" when we are at the airport.

I could, of course, provide a dictionary definition of "suspicious" as
something that is, "out of the ordinary, especially when percieved to be
dangerous". I could then argue that since I have never seen any armed
pilots at any GA airport, seeing one would qualify as something "out of the
ordinary" in my experience, and that would be enough for me to regard it as
"suspicious".

I could also argue that if it is, as you assert, your right to carry a
weapon at all times, it is also my right to carry a cell phone and to call
the police whenever I feel that such a phone call is warranted.

But I won't make any of those arguments, because I would just get a bunch of
static about doing so. Instead, I will simply point you to the specific
items on AOPA's Airport Watch Security Checklist
(http://www.aopa.org/asn/watch.html#use), one of which is "Dangerous cargo
or loads - explosives, chemicals, openly displayed weapons - being loaded
into an airplane."

Go ahead mate, flame away to your heart's content. I'm just trying to do
what I think is right here, but I know that won't be good enough for you.
