Honest question: Don't you think LE would need a little more than just their "opinion" before they name somebody as a suspect and state right out that they know the suspect is lying? That sounds like fact, not opinion, to me. IMO
Although LE has stated as fact that they "know" the suspects are lying, in reality, I don't think it's even possible. Sure, it sounds like "fact" when it's said, but to "know" something it actually has to be based on facts, yet it seems to me that the "knowledge" LE professes to have is based on less than facts. IMO, what we really have are just more opinions . . . . Opinions from higher authorities.
I don't think Bowerman would have labeled the parents suspects when he did had Klein not jumped the gun. JMOO
