I have seen some of Gray's videos and have found them to be very helpful in visualizing the way the crime may have unfolded.
However, Indiana State Police Sgt. Jerry Holeman has made an interesting comment about the reenactment videos. I don't know if he is referring to the videos made by Gray or by Anthony Greeno or by someone else (or by all of them).
Here's what Sargent Holeman said: “The videos help us know that people don’t know the true details, because the facts haven’t been released,” Holeman says. “People watch the news and think they are picking up on things, but it’s false. Nothing out there is accurate, which only leads to more false tips.”
In addressing concerns that police have held back too many details on such a high-profile case, Holeman said that is standard protocol for ongoing investigations. He said, "We do that so when we get key evidence, only the killer or killers know the cause of death. We don’t release it to the media because then everyone and their brother would know, and it’s common to get false confessions from mentally disturbed people. So we’re trying to keep the details close to our vests.”
