Only a video which has not been tampered with is valid and even that can be phoney because taping can be stopped, omitting parts of a continuing scenario, and restarted.
What we do know for certain is that Howard had a "motive" behind each tape he made beginning with the "Danny and his sister and Mom" tape. The "I hate Mommy", the marriage tape, the "screaming at the baby"...your mommy is dead tape all go to motive to "the money".
The SOB lied like a rug when he said "he was the biological father" according to his calendar on Larry King live. That interview is where Howard is "speaking for Anna", professing his "secret love", professing he is the father, professing they will marry soon.
Anna had become part of his script. It would be just another role for her...full of lies. It was okay to her at the time...she didn't know SHE was on his hit list.
Has Howard even had sex with a woman? Where are these people? Why are there no characters in his past to vouch for him BEFORE ANNA...No women, no men...(except Rale).
It might be a good thing to put the tapes in order of time...except there's no time stamp and even that can be altered.
Did Danny stay awake during his entire flight to the Bahamas? They said his papers were not complete...it lacked the address of the Horizons. Why?
