So, my junior criminologist over here took a look at the second set of photos and pointed out some interesting details which I missed.
First, he noticed a clear glass measuring cup with red markings behind the bottles of vitamins. Why would that be on a office desk?
Secondly, he pointed out that the body language between Long and the young seated man in the black shirt is extremely unusual. He said that he found it odd that the younger man would grasp Bishop Long by the upper arm and lean towards him. He said that should be the reverse as it's an authoritative gesture. He said that as a young 21 year old man, he would never grasp an older man's upper arm in such a way. He also noted that the young man was most definitely in Bishop Long's space--far closer than most men feel comfortable. He said that Long seemed to hardly be aware of the man and almost ignoring him.
Then, he pointed out that all three young men, while somewhat unique in their dress, share many similarities in body type and build. While Long is extremely built, all the young men are slender. He wondered about the earrings as he said that he'd think that Long would not approve of that given that he's said that gays are revolting. Older, more traditional men still can equate earrings on men with being gay and he said that he felt that if they'd been in an academy that wouldn't be allowed.
I might need to encourage this young man to get his own WS account. I have to say that I was impressed. He has been paying attention in his criminology classes.
