Rape conviction in Pakistan (and India) is a difficult goal to achieve for the reason that we are still following an archaic, neo-colonial legal system that needs to be scrapped ASAP. It is flawed on numerous levels and drafted keeping in mind that higher offices will be occupied by individuals from Britannia who will not share the subject society's biases and beliefs. Here's a brief step ladder system that disqualifies rape cases so that there are zero conviction:
1. Rape carried out by locals, baradari system comes into play, matter is buried for good, victim married off to rapists.
2. If the victim protests, elders intervene and try to impose a solution which may see the victim killed or married off to the rapists.
3. If the victim persists (and survives), the matter reaches local police who will avoid becoming involved in "Internal Family Matters" because they are also from the local populace and will tell the victim of the humiliation she will have to face and encourage her instead to marry the rapists.n
4. When the higher matter goes to the lower courts, the rapists can easily blame the victim of being a woman of low character and bribe the judge to work for an out of court settlement that, you guessed it, urges the victim to marry her rapists.
5. The case reaches the higher courts, if by some miracle the victim and her family are not dead yet and they keep issuing date after date until finally the case is disqualified for lack of evidence.
Keep in mind that this doesn't happen in Pakistan alone, this is a common phenomena in the entire sub-continent and it requires more than cheap point scoring and finger pointing to overcome, a more determined effort is needed to ensure that our societies and kin can foster to their true potential.
