the ones i talk of , have been identified as displaying sociopathic tendencies - i worked in health for 6 years in A & D Treatment , and was part of a multidisciplinary team that included psychiatrists and at times forensic psychiatrists , my role was also to receive prisoners on pre release etc , my last client was released from Jika Jika...remember that horror ..i was trained to deal with them and yes i agree , it is damn near impossible to identify a sociopath by sight alone - it takes a long time to piece the jigsaw together so to speak - it is only through thorough testing, complete history etc etc , that you can truly identify them
The worst of the worst which make up a extremely small group are rare - very rare , but something you will never forget if you do happen to meet one, and i dont say that lightly
