Sounds like the officer was being nice in letting the perp empty the truck of personal effects before being impounded:
https://ktla.com/2019/08/12/large-la...-in-riverside/Witness Charles Childress said the GMC pickup appeared to have been pulled over for some time before gunfire erupted.
Childress said he was driving to Sycamore Canyon Park with his dog when he saw the truck pulled over with the driver unloading property.
When Childress returned from the park about 10 or 20 minutes later, gunshots were ringing out.
