B Mr. Peters has a legal handgun to protect his home against intruders and against the
increasing crime in his neighborhood. One
night, Takeshi, a 16-year-old Japanese
exchange student, walks up Mr. Peters's
driveway looking for a party. Takeshi thinks
Mr. Peters is hosting the party and begins
yelling and waving his arms. Mr. Peters gets
scared, retrieves his handgun, and points it at
Takeshi while yelling "Freeze!" Takeshi does
not understand English and keeps walking
toward Mr. Peters. Thinking he is an intruder,
Mr. Peters shoots and kills Takeshi at the
front steps of his house. Mr. Peters is
charged with first-degree murder. Does he
have a defense?
