"...Sgt. David Dominguez and police officer Thomas Wever were driving down 208th Street near Barcia's home when they heard what they thought was a rock hit their car. They decided to search for who did it, and called for back up...."
This part is craziness.
IOW the COP was PISSED that someone threw a rock at his car and was acting like a pissed *ssh*le. He was going to make someone pay. I submit the cop is lucky he was shot first in his vest.
