JUDGING BY THIS REPORT, the guy should be treated as a hero, not locked up:

A Chinese martial arts expert was in custody yesterday after turning the tables on four burglars armed with knives, killing two of them and seriously wounding a third.

The 28-year-old man, known as “the doctor” for his practice of acupuncture and traditional Chinese medicine, managed to seize one of the two knives carried by his assailants and saw off the entire group with the ferocity of his reaction.

Magistrates in the central Italian town of Empoli are now seeking to establish whether his self-defence constituted an excessive use of force. . . .

Disappointed by their meagre booty, the attackers allegedly threatened to rape the two women unless they told them where the rest of their money was hidden.

At this point the doctor managed to free himself, seize a knife from one of the aggressors and deliver a series of lethal stab wounds.

There’s some question as to whether he pursued them once they decided to flee. I don’t know much about Italian law, but under American law that would generally be a no-no, though on these facts it sounds rather admirable.
