Interesting Thoughts on Gun Ownership: Self-Defense or Problem?

There is an interesting online discussion at Quora, including comments by a number of gun owners and firearm trainers.  The topic was whether owning a gun for self-defense was more of a problem than it was worth.  There are a lot of thoughtful comments, often based on where exactly the person in question lived, and an emphasis on the need for regular training and gun maintenance.  It's well worth a read (h/t John Scalzi)
