I was still very much in when we we're asked to pose for a family pic by the CO wife including our names. And at the next meeting we got the pic back with a text below stipulating who it came from, etc. I thought back then (4-5 years ago) that it was nice yet very strange. Something just didn't feel right. I guess intuition.
Yes, at my last CO visit, the CO and his wife handed out goodie bags to all the kids and asked for a pic of all the children (we have a LOT in our hall).
It could very well be that the CO and his wife are tasked with the additional duty of serving as scouting out potential actors/models for the WT art and video departments. (Keep your eye out for photogenic families, kids, etc., snap some innocent group pics, and include in your congregation report back to HQ with their names and spiritual status.)
I know first-hand they've plucked kids straight out of Bethel tour groups to use in video productions that day (after confirming their families spiritual "health", of course) when they're desperate.
