The question put fairly: Would allowing concealed carry on base...

Would allowing concealed carry on military bases have the net effect of increasing or decreasing the total number of fatal gunshots and non-fatal shooting injuries that occur on military bases?

Net. Effect. Of.

Policy is (one hopes) about net effects, not colorful annecdotes about freak instances. (You know the sort... George Lucas claims to have been thrown clear of a fiery crash in his teens because he wasn't wearing his seat-belt. Whatever. Cool story bro... but seat belts save thousands of net lives.).

I heard a guy on CNN talking about the Malaysian airplane and bemoaning the fact that if the pilot got the co-pilot out of the cockpit he could then lock him out and nobody would be able to force their way in to stop a suicidal pilot because the doors are heavily reinforced.

Oh no! Reinforced cockpit doors. Obvious insanity. Why did we ever do such a crazy thing? Oh, right... 9/11. It is a poor idea to let the passengers fly the plane, even though a secure cockpit allows a pilot to take his sweet time committing suicide.

The question is not whether an unsecured cockpit might have been handy on that one Malaysian plane flight. The question is the net effect of securing cockpits.

1. How can you say for sure?

Maybe more guns means more people would commit gun violence.

2. You may be misperceiving my argument.

I am saying that more guns means more net shootings.
