Some months ago my 6 year old granddaughter saw me watching a Medical Detectives or some other reality program on murderers and she she made a profound statement to me.
Granddad, have you noticed that all murderers have moustaches. This was some months ago and since then I have been making a mental note and so far there has not been one who did not have a moustache at the time of his crime.
My late father always said to me “never trust a man with facial hair”.
Could there be any link between a man with facial hair and a propensity to commit a crime?
