well there are Mutawas,.. lately they are lil active as well.. but K.S.A is a completely different place now.. Jeddah, Riyadh and Khober are pretty much like open cities, rest are same medieval ones.
To your surprise you can find saudi women, without face and head covering and in somewhat western deresses now in the streets and malls of Jeddah Riyadh and Khobar..
may be its true but i didnt found any with out abaya in any mall of riyadh. saw that in khobar but never in riyadh.
BTW i am also in riyadh right now
