I think he's saying that the accident resulted from egregious negligence. Sometimes accidents really are extremely difficult to prevent, like when you strike and kill a pedestrian who emerges suddenly while you're driving slower than the speed limit in very poor visibility. But sometimes accidents come about because deliberately undertake actions that a reasonable person can expect will result in killings. Like when you decide to drive home after consuming 8 shots of Jägermeister and accidentally kill a pedestrian. Both situations are accidental. But in one case, the police won't do anything while in the other case, you're going to go to prison for a long time.
