Contrary to mirror.co.uk report, CNN says Baltimore shooter is a black man. I don’t think they would miss an opportunity to report a white on black shooting, but they aren’t. https://www.cnn.com/2019/04/28/us/baltimore-shooting/index.html

"A black man approached an intersection where two cookouts were taking place on opposite sides of the street and started "firing indiscriminately into the crowd," said Harrison.

It appears that the gunman targeted one or more people in the crowd, Harrison said. Investigators are trying to determine if the two cookouts were connected."

Sounds like a targeted hit.
