On August 10, 1999, an armed gunman entered the North Valley Jewish Community Center during a summer day-camp program and opened fi re in Granada Hills, California. One month earlier a White supremacist murdered Ricky Byrdsong, a Black basketball coach at Northwestern University, and then began shooting people who were leaving a synagogue in the Chicago suburbs. Th irteen children were killed on April 18, 2000 by two White teenage gunmen in Littleton, Colorado. After a series of shootings revealed and demonstrated the ease with which people (particularly White male teenagers) could purchase and secure deadly weapons without a license, background check, or restrictions on quantity of guns, a movement for increased regulation of guns took off led by a White mother.
