If you want Resistance vs Civilian why not make Resistance friendly to nobody and then group the civvies under either West or East?
However, having read the thread, I confess I don't understand what the problem is. In the first post you write
police do not engage the civilians and visa versa
but in the later posts you complain that "they are killing each other." What am I missing?
