Amina,
In my personal opinion, if a reasonable environment develops in pakistan and men begin to give due respect to women and women also live under the constraints mentioned in Islam , then there is no ambiguity in serving of women in such depts.But this is utopia.Under present circumstances when talibans , extremists, and chavionists are every where and looking for their prey it is really difficult for women to face such hardships.But I like and want women to touch skies and occupy all fields of life and try to help in the amelioration of the poor state of the poor strata of our society and exterminate crimes and criminals.Amina, not all the males are chavionists.And infact Adil only tried to show the hurdles women face in such depts.Sister Amina, men are not your(women) enemies before they are men they are your brothers and father .So We also want you to have a successfull life.But you should be able to distinguish between man and beast.

Thanks and regards
