The U.S. minority groups face discriminations in education. According to a report issued by the U.S. Bureau of Census, 33 percent of the non-Hispanic white has college degrees, proportion of the black was only 20 percent and Hispanic was 13 percent (US Bureau of Census, April 27, 2009, www.census.gov). According to a report, from 2003 to 2008, 61 percent of black applicants and 46 percent of Mexican-American applicants were denied acceptance at all of the law schools to which they applied, compared with 34 percent of white applicants (The New York Times, January 7, 2010). African-American children accounted for only 17 percent of the U.S. public school students, but accounted for 32 percent of the total number which were expelled from the schools. According to a research by the University of North Carolina and Michigan State University, most of the black juvenile believed that they were victims of racial discrimination (Science Daily, April 29, 2009). According to another study conducted among 5,000 children in Birmingham, Ala., Houston and Los Angeles, prejudice was reported by 20 percent of blacks and 15 percent of Hispanics. The study showed that racial discrimination was an important cause to mental health problems for children of varied races. Hispanic children who reported racism were more than three times as likely as other children to have symptoms of depression, blacks were more than twice as likely (USA Today, May 5, 2009).

Racial discrimination in law enforcement and judicial system is very distinct. According to the U.S. Department of Justice, by the end of 2008, 3,161 men and 149 women per 100,000 persons in the U.S. black population were under imprisonment (www.ojp.usdoj.gov). The number of life imprisonment without parole given to African-American young people was ten times of that given to white young people in 25 states. The figure in California was 18 times. In major U.S. cities, there are more than one million people who were stopped and questioned by police in streets, nearly 90 percent of them were minority males. Among those questioned, 50 percent were African-Americans and 30 percent were Hispanics. Only 10 percent were white people (The China Press, October 9, 2009). A report released by New York City Police Department, of the people involved in police shootings whose ethnicity could be determined in 2008, 75 percent were black, 22 percent were Hispanic; and 3 percent were white (The New York Times, November 17, 2009). According to a report by Human Rights Watch, from 1980 to 2007, the ratio of the African-Americans being arrested for dealing drugs across the U.S. was 2.8 to 5.5 times of that of the white (www.hrw.org, March 2, 2009).

Since the Sept. 11 event, discrimination against Muslims is increasing. Nearly 58 percent of Americans think Muslims are subject to "a lot" of discrimination, according to two combined surveys released by the Pew Research Center. About 73 percent of young people aged 18 to 29 are more likely to say Muslims are the most discriminated against (http://www.washingtontimes.com, September 10, 2009).

Immigrants live in misery. According to a report by the U.S. branch of Amnesty International, more than 300,000 illegal immigrants were detained by U.S. immigration authorities each year, and the illegal immigrants under custody exceeded 30,000 for each single day (World Journal, March 26, 2009). At the same time, hundreds of legal immigrants were put under arrest, denied entry or even sent back under escort every year (Sing Tao Daily, April 13, 2009). A report released by the Constitution Project and Human Rights Watch revealed that from 1999 to 2008, about 1.4 million detained immigrants were transferred. Tens of thousands of longtime residents of cities like Los Angeles and Philadelphia were sent, by force, to remote immigrant jails in Texas or Louisiana (The New York Times, November 2, 2009). The New York City Bar Association received a startling petition in October 2008 which was signed by 100 men, all locked up without criminal charges in the Varick Street Detention Facility in the middle of Manhattan. The letter described their cramped, filthy quarters where dire medical needs were ignored and hungry prisoners were put to work for 1 dollar a day (The New York Times, November 2, 2009). Some detained women who were still in lactation period were denied breast pumps in the facilities, resulting in fever, pain, mastitis, and the inability to continue breastfeeding upon release (www.hrw.org, March 16, 2009). A total of 104 people have died while in custody of the Immigration and Customs Enforcement agency since October, 2003 (The Wall Street Journal, August 18, 2009).
