Yes, the bill in Pakistan to defend and protect women against honor killings is a huge step in the right direction. It shows that the legislative body is saying, "Enough! No more!" This will have strong ripples into every sector of society in Pakistan. It will shift the mentality in the right direction.
Civil authorities continue to uphold the popular system of honor killings in Pakistan. Many would be murderers walk away free as they are able to obtain forgiveness from other family members. Keep in mind this is a male dominated mindset and women are still considered to be property not equal under the law.
The new law is a start and goes a long way towards stopping rapes and honor killings, but it is only a small step. Even the laws in countries like the United States and Canada do not have strong enough laws to prevent rape and protect rape victims from further harm.
With corrupt justice systems, one never knows what is truly going on. Similarly to how people have been wrongfully convicted in the past, this new law passed in Pakistan will not be able to fully defend victims of honor killings because it is way too hard to define the specifics regarding them.
