When we leave the house, most of us pack a Batman type utility belt worth of stuff. Gun, spare mag, flashlight, cell phone, lawyers business card, etc. Lots of us carry when we are at home. But do you also carry all the other accouterments? Especially your cell phone? If you had to make a quick escape to another room because of a home invasion, or heard a noise, you might not have a phone handy. If you always carried it, it would be accessible.
