A government efficiency expert has observed that almost all provisional arrests meet the standards for adequacy of evidence that the watch commanders enforce. The expert has therefore recommended that because the officers time spent obtai

But if it was so commonplace, why was it listedmore often for wealthy households? Perhaps the more earthenwarepeople had, the m
