§ Mr. Lubbock
asked the Secretary of State for the Home Department whether he has studied the evidence of a correlation between chromosome abnormalities and criminal behaviour accumulated by Dr. M. D. Casey of Sheffield University, a copy of which has been sent to him; and if he will sponsor further research on this subject.
§ Mr. Roy Jenkins
I am well aware of Dr. Casey's work. As the published work indicates, some of the research on this subject was undertaken in prison with the voluntary co-operation of prisoners. Facilities have been granted for more extensive research in prisons by several workers in this field on condition that prisoners are willing to co-operate.
