This is JMO, but I felt like the friends of SS were all weird, except Ryan, the one who knew SS as a younger teen and then cut contact.
I don't discount what they shared based on them seeming like guys I wouldn't personally choose to hang out with, but the kinds of things they shared about themselves and their friendships with SS made me a bit uncomfortable listening in general at times.
So, I take not saying anything kind about MS in that context. He'a also kind of a strange seeming, guy a bit socially different, IMO. Probably in shock also. and in some ways I felt the friends were also making some excuses for SS and maybe for themselves for not noticing what he was really capable of? It could be something along those lines. Maybe he even feels guilty for not picking up on things?
Another thing I noticed throughout ALL of the interviews is some weird almost blaming of MS by different people. Some of the callers suggesting crap like MS could have been "groomed so well that she was in love with SS". Her own mom, JS seems to focus more on telling is what was "wrong" with MS--"She is forgetful, she has ADHD, she wanted to do ____". It get a weird feeling from most of the people we "know" in this case. They're all connected to one another via SS, so makes sense to me....
Really, the person who said the nicest things about MS, was SS when he was putting on his act. How sick and twisted is THAT?
