For good reason. Good catch and good, close reading, guys. I missed it, because I had read an earlier story.
Chief Deputy Sheriff Manuel Longoria said Vann was responding to a call for an accidental shooting in eastern Bexar County. He had stopped for a red light in the left westbound lane on Rigsby, just east of the Loop 410 overpass, "when someone rolls up on his right and just opens up, firing multiple shots."
The bullets shattered the front and rear passenger windows. Authorities said they were not sure how many bullets were fired; Longoria said numerous spent cartridges were recovered around the shot-out cruiser.
If a passenger in the white car did the shooting, he did it across the driver or from the backseat. Since the rear passenger window was shot out, I think the shooting was done from the backseat, or else the shooter's car was not paralell to the cruiser.
The journalist and editor (and I) responsible for this story obviously did not pay as close attention as did you guys. :-)
Thanks. That makes it much clearer. Looks most like a gang initiation then. (Could be that they were following him looking for their chance, but more likely any cop would have done.)
