"On computers recovered from his flat, police found images of men holding their hands around the necks of women during sex"
The CPS thought this was pertinent to whether the murder of Jo Yates was intentional or not. Also that he had been with prostitutes. Fortunately in this case the Judge ruled this evidence in-admissible and a convictions was secured anyway. But you can see what the CPS think. Being with a prostitute or seeing porn "of men holding their hands around the necks of women during sex", makes you a sexual weirdo capable of murder....
More backing for those who support the UK's 'extreme porn' law.
Edit: further story on this in particular

Pictures of women in the boots of cars is weird though.
