As far as I am concerned and as one commenter posted on the item:
"The law should be blind, be it to race, religion or gender."
i.e the law should not discriminate in any way, in the eyes of the law, put in front of a jury everybody should be considered equal.
As a point of interest I do not believe that prison is necessarily the best punishment in a large amount of cases. Like the author (Ms Mary Riddell) I believe that it is often the case that the funds spent incarcerating someone could be better put to use rehabilitating with community sentences. However this would be irrespective of gender and whether or not the punishment is the correct one given the nature of the crime.
