Yes, I have given much thought to it, sure. Every situation's different. It's entirely possible there might be an opportunity involving proximity, or lack of attention, or blocking his/their sight of my drawing. It could be uglier or simpler when there are multiple attackers, depending on how they attempt to control the situation, distance from me, etc. Generally speaking, I'd say it would be a "losing proposition," as some have suggested. A mugging or robbery is a bad spot to be in, but I'll do
Have you given thought to drawing on a loaded gun? I'll bet you have.
