East Asian Americans also commit crimes at a disproportionately lower rate than other racial and ethnic groups in the United States despite a younger average age, and higher family stability. However, a side effect of the model minority construct may be a downplaying of the presence of East Asian criminal behavior and gangs in several cities, including New York City, Los Angeles, San Francisco, Houston, and Seattle as well as in the state of Hawaii. Occasionally however, news of East Asian American criminals receive widespread media coverage, such as the infamous Han Twins Murder Conspiracy in 1996, and the 1996 United States campaign finance controversy where several prominent Chinese American businessmen were convicted of violating various campaign finance laws. Other incidents include the shooting rampage by physics student Gang Lu at the University of Iowa and Norman Hsu, a Wharton School graduate, businessman and former campaign donor to Hillary Clinton who was captured after being a fugitive for sixteen years for failing to appear at a sentencing for a felony fraud conviction. Other examples of criminal and unethical behavior are in contrast to the model minority construct.
