ISIS orders female genital mutilation in Iraq

[MaxQue]

ick, I hate reading about this topic.  In Egypt it's between 78%-97% depending on how one defines things.  This is despite it being flat illegal since 2007 and mostly illegal since the 90s.

Forgive my ignorance, but how can something like this be 'mostly' illegal? Enforcement issues or something else?

I suppose there was exceptions and loopholes.
