So it makes sense to blame the police for starting a commotion that set in motion a situation that would not have arisen otherwise.

Just playing devil's advocate, but the only difference I see here is that the government has a monopoly on law and they hire the police, and the killer that person allegedly hired is not working for the law the government made, but for the law that person made.

So there's no need to pontificate here. This is just the difference between an organization having a monopoly on violence and then acting surprised when others want to make contracts with rules based on violence as well.

Not to mention our current president has ordered the murder of US citizens before but no one is arresting him.
