I cant find a specific link (4 hours of congressional hearings) but I listened to Rep. John Lewis, of Georgia additional remarks on the recent black shootings at the House Oversight and Government Reform Committee with FBI Director, on July 7. This was before the Dallas shootings happened later that night (last night).
Rep. Lewis said his wife woke up that morning in tears at the latest news of the young woman who along with her child watched her boyfriend die in a traffic stop, said that he had good and difficult relations with LE on so many different levels in his lifetime, but emphasized that in his lifetime as a black man he has been stopped 50 million times. He was imploring the FBI Director to have his department take a closer look.
It is a trickle up effect we are in need of; elected officials, leaders of law enforcement, civil rights, educators, and healthcare to all have a closer look at a growing crisis.
