They were interesting NOT disturbing. We already know they tried to set up security guards as the culprits. Was there something 'disturbing' later in the blog?
"Disturbing" was a quote from the blog. In my opinion the blog wording was a caution for squeamish readers.
I also found this observation quite interesting:
"In the green room at Fox last night I was discussing the known facts and some conjectures with NYPD Detective Gil Alba. He agreed that it would take some intelligence and sophistication to map this all out. I agree. So far everyone eventually held in this case was first questioned as a witness. Last night the elder Van der Sloot was brought in and spent four hours with authorities being questioned as a possible witness. What that might mean, I don't know."
