Could very well be, it is also rare for the officer to be stripped of equipment.
Many have said why don’t officers ride two to a car to prevent these thing from happening? Two to a car, ten to a car, there is no guarantee on these things. Four CHP officers were killed by two gunmen on a suspicious vehicle stop known as the Newhall shooting.
The Unites States probably cannot afford to have two officers in every car as either it would be prohibitively expensive or would drain resources away from areas to be patrolled.
If this were a random shooting that resulted from the victim bursting in on a crime in progress, there would be signs of a panicked exit with random pieces of evidence left around the crime scene. Instead, it seems to be perfectly devoid of evidence, possibly including shell casings, meaning a remarkably quick and careful cleanup or that the assassins deliberately used a revolver, a handgun that does not automatically eject spent cartridges. Even the mixed race makeup of the hit team suggests an assassination, terrorist groups like BLM being so often composed of radical blacks and whites.
