In Washington State the law reads that a cop (or anyone) can shoot a person fleeing from a felony (so assualt, burglary, stolen vehicle, etc.) The idea of a threat to anyone doesn’t have to be there.
However, on other threads there has been discussions of Supreme Court rulings that in some cases will over rule those laws if it is deemed that a person’s rights have been violated.
But fleeing itself is not a felony, and one needs to establish the presence of a felony first.
