The Twelve Tables forbid a thief— that is to say,
 a plunderer and a robber—to be slain by day, even when you catch him, a self-evident
 enemy, within your walls. “Unless he defends himself with a weapon,” says
 the law; not even if he has come with a weapon; unless he uses it, and resists; “you
 shall not kill him. If he resists, endoplorato ,” that
 is to say, raise an outcry, that people may hear you and come to your aid. What can be added
 more to this merciful view of the case, when they did not allow that it might be lawful for a
 man to defend his own life in his own house without witnesses and umpires?
