"On a hot summer afternoon in August 1998, 37-year-old U.S. Army Sergeant First Class Rossano V. Gerald and his young son Gregory drove across the Oklahoma border into a nightmare. A career soldier and a highly decorated veteran of Desert Storm and Operation United Shield in Somalia, SFC Gerald, a black man of Panamanian descent, found that he could not travel more than 30 minutes through the state without being stopped twice: first by the Roland City Police Department, and then by the Oklahoma Highway Patrol.
During the second stop, which lasted two-and-half hours, the troopers terrorized SFC Gerald's 12-year-old son with a police dog, placed both father and son in a closed car with the air conditioning off and fans blowing hot air, and warned that the dog would attack if they attempted to escape. Halfway through the episode – perhaps realizing the extent of their lawlessness – the troopers shut off the patrol car's video evidence camera.
Perhaps, too, the officers understood the power of an image to stir people to action. SFC Gerald was only an infant in 1963 when a stunned nation watched on television as Birmingham Police Commissioner "Bull" Connor used powerful fire hoses and vicious police attack dogs against nonviolent black civil rights protesters. That incident, and Martin Luther King, Jr.'s stirring I Have a Dream speech at the historic march on Washington in August of that year, were the low and high points, respectively, of the great era of civil rights legislation: the 1964 Civil Rights Act and the 1965 Voting Rights Act.
How did it come to be, then, that 35 years later SFC Gerald found himself standing on the side of a dusty road next to a barking police dog, listening to his son weep while officers rummaged through his belongings simply because he was black?"

And it's not gotten better in the years since this particular example.
