I'm armed security at my church. Sunday, about 2/3 of the way in - a guy who used to come a lot, but disappeared about 9 months ago walked in. He was carrying something in both hands. The foyer light was turned off. I never knew that without that foyer light, that the light coming through the front door glass would only silhouette someone coming through the door. I didn't recognize him, only that he wasn't one of our regular members.
He waved as I moved in my chair to face him and started to get up. That bought just enough time for me to see that he was holding his hat, some papers, and a couple other items together in his hands as he walked in. Not going to lie, I had spent a split-second in that mental territory of "aw crap, I don't want to have to do this today". I felt guilty later for even having that thought cross my mind. Then I felt guilty for not being better prepared.
I fear the church shooting acts will only continue to increase. It is a shame that we even have to worry about it at all.
From now on, I'll check that foyer light every day as I come in too.
