Coppers stayed alive by trickery. That's how it worked. You had your Watch Houses with the big blue lights outside, and you made certain there were always burly watchmen visible in the big public places, and you swanked around like you owned the place. But you didn't own it. It was all smoke & mirrors. You magicked a little policeman into everyone's head. You relied on people giving in, knowing the rules. But in truth a hundred well-armed people could wipe out the Watch, if they knew what they were doing. Once some madman finds out that a copper taken unawares dies just like anyone else, the spell is broken.
