No, that is not a typo. That statistic comes from the NYPD and yes, it likely is an underestimate.
While the model minority myth promotes the belief that all Asian Americans live charmed lives, Anti-Asian violence has had a long history in the United States. And the perpetrators of that violence typically have not been adequately punished. As far back as 1879, a judge acquitted a defendant for the murder of a Chinese laborer in Texas because "there ain't a damn line nowhere [in the Revised Statutes of Texas] that makes it illegal to kill a Chinaman." More recently, Vincent Chin was beaten to death in the 1980s by two White men who believed that Asian immigrants were taking away American jobs. Mr. Chin's murderers were sentenced to probation because "[t]hese aren't the kind of men you send to jail." (As an aside, the Academy Award-nominated film Who Killed Vincent Chin? provides a great point of reference about violence against Asian Americans.) And in late January 2021, an octogenarian Thai immigrant, Mr. Ratanapakdee, was beaten and killed while out for his morning walk in the Bay Area. His murderer has not yet been tried. Now is a good time for the judiciary to send a strong message about hate crimes generally, and Anti-Asian violence more specifically.
It's important to consider the murder of Ratanapakdee against the historical backdrop of anti-Asian violence in America. Like crimes against other people of color, anti-Asian violence has been underscrutinized, underprosecuted and often condoned throughout US history.
