Mad Rocket Scientist takes on one of Heinlein's misused quotes "An armed society is a polite society". Oddly enough, he takes the pro-gun side to task in a way that is eye opening and refreshing.
I especially love the comparison to the navy and how each and every person on a ship is responsible for putting out fires although there are "dedicated" damage control teams to our professional police force and the responsibility we all have in fighting crime.
Give it a read. It's worth your time.
