Without hearing any testimony, especially if TM takes the stand in his own defense which I doubt he will, at this point thus far I would vote your arrogant and cold FBI above the law. If he just wanted to protect his daughter he could have put her on a plane out of country, claimed a burglar broke in, etc. But his time in grade with FBI and in TM's head, FBI background loving his sick daughter and pattern of having to cover for her and protect her, trumps a dead loyal father/husband/provider. TM had to do some quick quick thinking prior to making the 911 call. And if you listen to the 911 call, TM desperately didn't want to touch JC in my opinion nor render any help, etc It sort of sounded like he was trying to say to the 911 operator "No, he is beyond help I think, and he is a mess and covered in blood". In that instant, he sided with his sick daughter, the murderer, over the long term gentle giant family man. I strongly have the opinion he thought the FBI would protect he and his daughter at all costs.
In some way I guess I have to, in some way , respect TM for his love and protection of daughter, but enough is enough. If TM had just witnessed the scene, called 911, and went with insanity defense, maybe MM does 10-15 yrs somewhere receiving help. Either way I feel she will spend many yrs behind bars but she is taking TM down with her.....at her fathers direction and decision.
