Another case of white police officers using force on unarmed African-Americans is making news this week. A video of a McKinney, Texas police officer surfaced this weekend. In it, you can see the officer waving a gun at black teenagers and wrestling a teen girl in a bikini to the ground at a pool party. The officer is now on administrative leave. The incident happened at a private, community pool in a housing development. We take a step back and look at how the story of privatizing pools coincides with the story of de-segregation.
