Eileen Ormsby, who wrote two books about the Dark Web that cited the Allwine case, said of Lanterman:

He had absolutely no idea what he was talking about in relation to either. I was gobsmacked that no rebuttal expert was called as they would have wiped the floor with him. He also denigrated the law enforcement forensics officers involved..."
