Talk about putting words in someone's mouth!! John expressed an OPINION and he also expressed that he would like to keep that OPINION to himself. You SEEM to be jumping the gun!!
Hopefully John will enlighten us shortly.
He did say "there is every possibility that a third party knew of the plan ahead of time and could also have faced a conspiracy to murder charge."
He then said when asked who he meant "I'm afraid I can't say for legal reasons."
Sounds to me like he knows something ...
