Depends on the details right?
I mean if he's just got some big TV in a room asking guys to cast some pics to talk about what they did over the summer, I mean that seems like an ok team bonding type thing right? Don't see any problem there.
If he's standing up there saying gimme your phone and I'll choose what to cast, I'll just scroll past the nudies your GF sent, promise, well, not good.
I have a hard time thinking anyone decides as a bonding exercise I'll look through your pics and decide what to share, I think scenario 1 is more likely, but I suppose that the nature of the investigation.
