I have made a conscious choice to not carry a gun. I support the right to do so, and will defend it vehemently. It's just not the right choice for me at this point in time.
There are two major reasons for that - the first is that I don't feel that I live the kind of life where carrying a gun on a regular basis is a good part of my EDC (Every Day Carry) kit. Two pocketknives, a flashlight, and my Leatherman Wave, sure. A gun is just extra weight for a one-tenth-of-one-percent chance of being the right tool.
The other reason is because I simply don't trust myself to carry right now.
On the night of October 22, 2007, I was mugged on my way to work (I was working graveyards doing technical product support in Seattle). I'll paste in some of my LiveJournal post from the next day and then talk about what the last almost six years have meant to me.
Note: Pictures inline, might be distressing for some.
