When I Started Looking At This Map About American Schools, I Did *Not* Expect That Bar To Go Up

After Brown v. Board of Education (more on that below), America specifically ordered many school districts to desegregate (aka stop having just one type of person at the school). This was supposed to make it more likely that African-American kids would be in schools with non-African-American kids … this is desegregation. It made it official: Separate but equal is unconstitutional. 
Turns out, our schools are even MORE segregated now. Even more separate.

X-Ray View Of The Crab Nebula
In 1054 AD, Chinese astronomers and others around the world noticed a new bright object in the sky. This “new star” was, in fact, the supernova explosion that created what is now called the Crab Nebula. At the center of the Crab Nebula is an extremely dense, rapidly rotating neutron star left behind by the explosion. The neutron star, also known as a pulsar, is spewing out a blizzard of high-energy particles, producing the expanding X-ray nebula seen by Chandra. In this new image, lower-energy X-rays from Chandra are red, medium energy X-rays are green, and the highest-energy X-rays are blue.

A second officer has been shot at. This time, a drive-by on the interstate. The officer was off-duty and has minor injuries resulting from broken glass. To be clear, the two shootings tonight are completely unrelated.
