Because there were lasers all over them and the cops were shooting as soon as they hit the snow bank.
Cox does not say that there was shooting as soon as they hit the snow bank. She says firing started after Finicum got out.

Excerpted here “While we bicker over whether or not the shooting was justified, we are all missing the bigger picture here.
Why was there a roadblock set up in the first place? Why was there such a display of force for something that had been peaceful up to this point? When we contrast this protest with the riots in Ferguson or Baltimore, why were they handled so differently? The answer to all these questions are the same; the Federal Government was trying to send a message. This protest wasn’t minorities against white cops and police brutality. It was The People versus the Federal Government. This group was traveling to speak to a crowd in another city to spread their message of, abuse of government power. They were exercising their rights to free speech and to peaceably assemble. Last time I checked, those rights are still guaranteed by the constitution.”
