Does accidental killing count? Like for example, there is an anti-AI protest in front of prominent AI company, things get rowdy and an AI researcher get accidentally hit in the head which causes death, but there was no intention of killing him/her.

"your honor, I couldn't have killed him, I voted NO on that very question on manifold markets:" new frontiers in digital alibis

uhhhhh let the record show i only voted YES because there's a lot of crazy mfs out there and the odds were really good

Do suicides count? Does AI killing someone count?

Suicides do not count. AI deliberately killing an AI researcher (for the stated goal of saving the world AI) does count.
