I find it very difficult to believe what is written on jeremybamber.org. it claims
In truth Jeremy Bamber has been examined by over 27 different psychologists, none of them have found him to have a personality disorder of any variety, nor any mental illness, nor any indication of psychopathy.
Now bare in mind psychologists are not psychiatrists, It is usually only a psychiatrist that can make a formal diagnosis. Unless your a psychologists with a doctorate like Dr Hare
The Hare psychopathy checklist (PCL-R) should only be used by experts. But apparently JB did not score high enough on this diagnostic but who done this examination? probably someone who supports his cause who does not know how to use it. Dr Hare has stated in the wrong hands you get a wrong result. However I think a genuine professional assessment on JB would be pointless by now as he would know what's happening and probably knows the diagnostic criteria enough to pass an examination of such by lying.
I am convinced he does have psychopathy simply by his look. Those with psychopathy tend to have a cold predatory gaze with no emotion in the eyes. They say with psychopaths the eyes don't match the mouth or the situation.
Would any normal individual have this expression on their face if they stand accused of killing their family?
It could be me but he has not emotion in his looks, like a reptile!

Then this photo, it seems like he is trying to smile or trying to hard to make a convincing smile.
