acting erratically

米国アラバマ州モービルにある南アラバマ大学のキャンパスで，裸姿で突飛な行動を見せていた男子新入生が同日未明、University Policeの警官に射殺されてしまいました。日本では考えられないかも知れませんが，アメリカの大学の多くはキャンパス内に専従の警察があります。悲劇は警察側の発表によると，学生がerratic (cally)な行動をとったためということですが，射殺という行動に疑問の声があがっています。erraticは「常軌を逸した，突飛な，奇異な」という意味で，かなり強い言葉です。（UG）

Campus officer kills naked freshman at University of South Alabama

(CNN) -- Authorities are investigating why a University of South Alabama officer fatally shot an 18-year-old freshman who they say was naked and acting erratically outside the campus police station early Saturday.
With few details of the shooting in the Gulf Coast city of Mobile, the student's mother and one of his friends said they could not understand how a six-year varsity wrestler and good-natured teenager could have died under such strange and sad circumstances.

According to a statement from the school, the campus police officer heard a loud banging noise on a window at the station at 1:23 a.m. CT (2:23 a.m. ET) Saturday. When he left the station to investigate, the school said, "he was confronted by a muscular, nude man who was acting erratically."

The man, later identified as Gilbert Thomas Collar, of Wetumpka, Alabama, repeatedly rushed and verbally challenged the officer in a fighting stance, the school said. The officer, whose name hasn't been released, drew his weapon and ordered Collar to stop, the school said. The officer retreated several times to try to calm the situation.

"When the individual continued to rush toward the officer in a threatening manner and ignored the officer's repeated commands to stop, the officer fired one shot with his police sidearm, which struck the chest of the assailant," the school statement said. "The individual fell to the ground, but he got up once more and continued to challenge the officer further before collapsing and expiring."
