Tragedies happen all the time, but the tragedies last week left so many of us asking more questions than there are answers.
- In Louisiana, a black man was killed by white police officers while being subdued on the ground.
- In Minnesota, a black man was killed by a white police officer during a routine traffic stop over a broken tail light.
- In Texas, five police officers were killed by a black sniper during a Black Lives Matter demonstration in Dallas.
