Solitary confinement: I can no longer isolate this convict, even for his own protection.
Street stop: That looks like a crime going down, but do I want to go through the hassle of all the paperwork involved? Or should I just drive on to the donut shop?
Interesting point. Not sure how you accomodate that; if you distinguish between protective solitary and punative solitary, suddenly every single solitary decision becomes instantly 'protective'.
