The racial incorporation process began with the civil rights movement of the 1960s affected American institutions and the urban environment. Although cities remain segregated by race, African-Americans and other population of different colors are increasingly. Perhaps the most troubling ones arise when Black people act out social roles that others do not expect or accept. These acts draw “color lines” that represent a fundamental fault line in present day American culture, especially for Black people who experience upward mobility. When such events take place, the effects can be fatal, as was the case for George Zimmerman. The killing of 17-year-old African-American Trayvon Martin. The event has touched off a fierce debate over race, violence, and equal treatment under the law. On February 26, CNN stated that Trayvon was visiting a house with his father in a gated townhouse community in Sanford, Florida (outside Orlando). Trayvon left the house and walked to the local 7-Eleven. On his way back, George Zimmerman, a white 28-year-old neighborhood watch captain, called the police because the boy looked “real suspicious,” according to a 911 call released late Friday. Even though the operator told Zimmerman not to pursue Trayvon, he did anyway, getting out of his car and confronting the boy. And according to the New York Times' Charles Blow, "Trayvon had a bag of Skittles and a can of iced tea. Zimmerman had a 9 millimeter handgun. The two allegedly engaged in a physical altercation. There was yelling, and then a gunshot. When police arrived, Trayvon was face down in the grass with a fatal bullet wound to the chest." Zimmerman was taken into custody, but said he acted in self-defense, so he was questioned and released with no charge. But, so far police have still not charged Zimmerman with a crime. The case has reignited a furious debate about racial profiling in society,
