You are not obligated to do anything in libertopia. The only active prohibition is “thou shalt not aggress against others or their rightful property”. Witnesses do not have to help or report. Anyway, I suggest you check this thread out, and read Nielsio’s ideas on reputation. I think he has a video in his channel specifically about it, but he talks about it in the podcast in that thread.
Basically, if you are a witness and you don’t help, even by reporting the crime, this sets red flags to the rest of the community that you are not a person who can be trusted. Kicking your own dog might not be a crime, but it sure as hell is going to be a warning to the community that you are not a safe person to be around.
Before we tackle the problem of child porn, let’s talk about hit men. If you hire a hit man, you have not committed the murder yourself. But you would still be complicit in the crime. In this case, your actions would definitely be criminal. But how does this apply to child porn? The person acquiring the video might not have contracted for the crime to be committed. He is only buying it after the fact.
Well, there are two ways to look at this. The first is, the man’s behavior is not criminal. He paid for a service regarding a crime that did take place, but he was not complicit in the crime itself. In this view, acquiring child porn and contracting a hit man are not analogous situations. However, this is where reputation comes into play. Sure, maybe the man with the child porn did not do anything criminal, but his behavior is a HUGE red flag to the rest of the community. This man supports crimes, even if they are after the fact. He is a danger to the community. It’s very likely that in a case such as this, this man would end up an outlaw.
The second way is, the man’s behavior is criminal. He was a complicit party. What happens next is just a matter of law.
Either way, I doubt people like this would be tolerated very much in libertopia.
