Yoshihiro Hattori - Afterwards

Afterwards

After the trial, Peairs told the press that he would never again own a gun.

The Japanese people were shocked not only by the killing, but by Peairs's acquittal. Shortly after the Hattori case, a Japanese exchange student, Takuma Ito, and a Japanese-American student, Go Matsura, were killed in a carjacking in San Pedro, California, and another Japanese exchange student, Masakazu Kuriyama was shot in Concord, California. Many Japanese reacted to these deaths as being similar symptoms of a sick society; TV Asahi commentator Takashi Wada put the feelings into words by asking, "But now, which society is more mature? The idea that you protect people by shooting guns is barbaric."

One million Americans and 1.65 million Japanese signed a petition urging stronger gun controls in the US; the petition was presented to Ambassador Walter Mondale on November 22, 1993, who delivered it to President Bill Clinton. Shortly thereafter, the Brady Bill was passed, and on December 3, 1993, Mondale presented Hattori's parents with a copy.

Suspicions of implicit racism in the acquittal of Peairs further gained traction when, shortly afterwards, a homeowner named Todd Vriesenga, inside his house in Grand Haven, Michigan, similarly shot and killed a 17-year-old named Adam Provencal through the front door. Vriesenga received a 16- to 24-month term for "reckless use of a firearm resulting in death", causing both Japanese and Asian-American advocacy groups to speculate on whether the difference between Vriesenga's conviction and Peairs's acquittal was related to the race of the victims. Other groups publicly stated that Vriesenga should have been convicted of the more severe charge of felony manslaughter.
