I guess it depends on if he was following orders to deploy the stop sticks and then it depends on if there was something out of the norm for the situation that was disregarded.I don't see how OHP is "responsible" for the Trooper's death, in the sense of placing blame/assigning fault. The criminal is responsible.
Having a conversation about the efficacy and necessity of high speed pursuits, and the policies governing them, is another discussion.
