This is one of those rare cases in which no matter how smart and wily officers are, bad things can still happen. Flat-out ambushes are relatively rare (see any typical year's FBI LEOKA report), but can still happen, and the only way to win is to think and act faster than your adversary. The idea of doing something, anything, even if it turns out later to be "wrong," is going to yield far better results than inaction.
A state officer has pointed out that these are the 8th LEOs to be attacked in that area of Washington state, of which 5 were killed.
