Dr. Kelly was a highly intelligent man.
The "suicide hypothesis" asks us to believe he incised his left wrist with the intention of killing himself.
It doesn't take too much intelligence to work out that cutting two wrists is likely to cause more blood loss than cutting one wrist.
So, given David Kelly's intelligence, why according to the "suicide hypothesis" didn't he cut his right wrist?
Many genuine attempted suicides cut both wrists.
Why didn't David Kelly?
I don't think it's explained by any cut tendons on the left side. The greater part of the grip on a knife comes from the thumb and middle and index fingers. So David Kelly ought to have been capable of cutting his right wrist to the same degree as any other supposed suicide.
So why didn't he do so?
According to the postmortem report, seemingly no tendons were severed:
This wound penetrated through to the level of the tendons in the flexor compartment and there was some damage to the tendons themselves, although none appear to be completely severed.
So, mechnically speaking, David Kelly ought to have been able to incise his right wrist too.
But he didn't.
For an intelligent man supposedly intent on killing himself (so the "suicide hypothesis" would have us believe) that failure to incise his right wrist is a bizarre and unintelligent omission.
It, quite simply, doesn't make sense.
