Rather than tackling this the 'usual' way I am going to turn it on its head.
IFF he were the killer then how did a Southern Country boy manage to put on such a brilliant Oscar winning performance at the flick of a switch? In order to have been the killer has to have been running to and fro being all things to all men, switching role of annoyed father, killer, angry father, killer, very worried father - there is no way he could have sustained that charade and not have tripped up.
Yes, he had been angry with his son. Any sensible adult would have been furious to see a kid lying on a skate board going down the road in traffic lane.
Later he was angry that Chris had done a vanishing act, despite fact that he knew they were going out for a meal that night. And they started to look for him.
As time went on the irritation changed to concern. He was the first to say they were looking for their son - to a cop in his patrol car. They then went home and called the police and filed MPR. If he had been the killer then I find it hard to believe that he would have increased the pressure on himself by alerting authorities sooner rather than later!
Added to this, he was also the only parent to contact Search And Rescue people to see if they could help.
Yes he was a very 'visible' person. Yes, there were anger issues that became even worse after the horrendous murder of his son. Yes there were issues deriving from both he and his wife's use of drugs and alcohol.
Yes he did know a lot of the local police force. However he was a drug informant for the police in Memphis Tenn. I believe - not West Memphis.
He was loud and volatile in his anger at the people he thought had killed his son. He hated the fact that the case gained even more notoriety and that the three who were convicted became the focal point of the case whilst the real victims were pushed into the background.
When I first became obsessed with the case I was reliably told that the only way the case would be resolved justly was for an alternative suspect to be exposed along with a lot of questions. Once past the conviction phase then the burden of proof is no longer down to the state but switches to the defense! Proving innocence with no alternative theory is a tough one. The best way forward is to high light others who maybe a better case could be made against. JMB being such a larger than life character was, for many, the obvious target. Sadly, many did not bother to examine thoroughly, and just stuck with pointing at JMB.
The camera likes him - but only playing himself! He is not Oscar winning material!!
There are still some who have him on their suspect list. Some even more certain after he took the trouble to go to the 'presentation of new evidence' meeting that the EDT held in 2007 before the legal team went public. He had some questions but was not, as far as I am led to believe, expecting to be persuaded by what he was told. But he was!
BTW if there is any hint of 'reasonable doubt' over guilt then it is not proven. Further more emotive language might be a game changer in court - but only if the evidence does not stack up and the prosecution have to resort to theatrics. In this case the whole satanic thing worked for them on gullible juries and small town dynamics.
Where the case is at now it can either not change and the wmfree are lumbered with the convictions for life and the families are left with no true justice. Not only is the burden of proof on what was the EDT, but so is the responsibility of finding who the killer most probably of is. THEN public pressure needs to be applied to the state Arkansas. As things stand they are able to state that the case is closed, they have their guilty pleas, the let them out as it was politically and financially expedient to do so. So which ever way anyone looks at it - the killer or killers walk free. Is that YOUR definition of 'Justice'?
