How popular/important do you have to be for your death by homicide to be labeled as an "assassination"? What if the homicide is for a private matter that's separate from their importance?

Does any political office count?

What about school board or a principal?

What about a chess champion?

What if you're the prime witness to a huge crime?

Military leaders? Chief of police?

Youtubers, podcasters?

CEO? Small bussiness owner? Manager of a store?

Does popularity matter, or is it only importance?

And lets say the leader of a country got killed, but its by their relative for, say, getting bulled as a kid, and the movive has nothing to do with their position of power? Does that count as an "assassination"?
