Slightly off thread but relevant I think with respect to arming people up to make society "safer"....
In certain countries carrying a firearm when committing a crime is a mandatory death penalty (Singapore).
Guess what, very, very, very little crime. In a country of 2 million plus (size of most large cities in the US?) a motorbike being stolen makes the national newspaper.
The answer is to not tolerate guns at all. It's only a matter of time before some idiot takes a gun off the pilot and where will we be?
Giving a gun to a citizen (I don't care if he is a pilot, pilots tend to reflect a cross section of society) is a BAD idea.
What's Airport Security for ?
