The payed off Diyah is mostly common in rural nomadic areas, you can neither jail (There are no jail cells in Miiyi) or execute someone for a crime( in fear of retaliation).  You pay a hefty fine as a punishment and are made to reconcile to prevent further violence.
Historically in Somalia the cities/states ,agricultural villages and coastal towns connected to sultanates people were either executed, put to trail (even trail by fire) and jailed.
During the two administrations after independence it was handled with severe punishment, policing and rape/killings were extremely rare as a consequence.
Same during the brief Islamic Courts Union era, where justice were mandated by non-clanal courts and parroling police units funded by business men.
It's important to understand this because the current situation in Somalia described by 
@Hodan from HR and 
@Angelina is deeply connected to collapse of the central state, which has been replaced with weak corrupt clan federalism,  that was imposed on Somalis from the outside.
So people as a consequence have turned to the private sector for employment & basic services(93% of the jobs) not the public sector(government) which is riddled with nepotism & discrimination and to their local clan leaders for justice and law because they don't trust the corrupt state.
When historically Clan elders were outside of politics concerned with rural welfare, and acted as mediators  and they were subject to and regulated by a over-arching non-clanal state actors and Sheikhs.
I encourage you all to read this to get an accurate understanding of the distortion of their role:
One of the recommendations:
Even the Kacaan government had a better grasp of their role than the current admin that distorts it as they were made into nabadoons tasked with only social-cultural communal issues.
And historically people all walks of life both men and women used to find employment in the cities/towns/villages pre-colonial era  and in the independence era/revolutionary era by the state as the main employer.  And foreign observers during the pre-colonial era remarked how justice was handled extremely well in the major towns.
So Somalis have to challenge and reform the system, instead of trying creating an image of a cultural status quo because it's not.
And we should broaden it to understand that it not only effects women badly but it affects all of us. Understanding that any one group or section that faces injustice is an injustice towards us all and that will make people act against it.
