I'm just guessing here, but maybe because Ingrid was a zealot? And she'd escalated as the years passed, finally to the point where she could mentally justify killing innocent bystanders. If she hadn't killed the cop in cold blood, and hadn't had her finger literally on the trigger, I'm not sure Duncan would have killed her.
