Honestly, I've always been one to tote around my phone--curse of this millennial generation--but I've never really thought of it as a tactical security device until as of late. And like OP mentioned, I've never really carried to go get the mail or take out the trash. But now, I'm finding myself making it part of my routine. I'm not churchgoer--although nothing against any of you who are, I just worship in my own way--so I don't have any real insight into security there. But if I did go, I'd take solace in knowing that some of my fellow brethren there were carrying. Also, having travelled to other countries, I've seen some things that have made me think lately. For instance, in some places around the world, there's armed security for everywhere including laundromats and McDonald's. They're hired out by third-party companies and mainly exist to help give jobs to those to need it. While a job boost would be nice, I think it would do wonders for people's peace of mind if we started doing the same. Not claiming to know all (if, any) of the answers, it's just a thought.
