Ron, thanks for the clarification on guns on planes. Nevertheless, the hijackings pretty much ended when guns were excluded in a serious manner. The 9/11 hijackings were very cleverly conceived, planned for many months, and could not be duplicated today. Allowing guns on planes does not seem wise if one looks at the history.

However, within factions armed individuals aren't likely to be found shoving someone aside to gain a place in line at the market.

And this (if true at all) is due to their carrying guns? How? Look, Ron, the world is eloquent testimony to the idiocy of the Heinlein quote. The availability and prevalence of guns in a society is more closely associated with violence, strife, and disorder than it is with anything that can be termed "polite". There are certainly arguments to be made for allowing them anyway, but let's face the facts rather than relying on discredited bromides. You guys have the second amendment on your side; the "gun grabbers" aren't going to reach their goal.
