Walton wasn't wearing his police uniform, but the bulletproof vest he wore had the large letters L.A.P.D front and back, which stood for Los Angeles Police Department.
Gao Guang, donning Walton's bulletproof vest, hurried outside, and then he looked toward two apartment buildings that weren't too far off in the distance.
The apartment buildings were on a block to the west, a linear distance of nearly one hundred meters, but by walking forward for just thirty to forty meters and then turning a corner, a car could drive straight up to the buildings.
The apartments seemed to be eight stories high, the sort of nondescript structures you'd find in this neighborhood, which wasn't likely to host luxury units, so the sniper could be hiding in any room within the complex.
However, a closer look from outside revealed the rooftop as the best shooting position, as only from there could one have enough height to oversee and seal off this house from a superior vantage point.
