Also, I'm not a lawyer, but I'm preeeeeetty sure arrest warrants don't come with an "invalid if suspect leaves the immediate area" disclaimer on them. I'm fairly sure I can't commit a crime in New York and become untouchable by Larry Law as soon as I cross into New Jersey. Again, I'm not a lawyer. If that's not in fact the case, then I've just hit upon a foolproof bank robbery plan.
We aren't talking about him just hopping state lines here. This is leaving the country entirely, which is MUCH harder to chase you over.
If you hop state lines, it becomes harder to arrest you since the police in the state you committed the crime aren't allowed to pursue justice outside of their state (jurisdiction), meaning they have to co-ordinate with the police in the area you are in order to bust you, which takes time to do, especially since the new state you've gone to isn't likely to have extensive records on you. You're not the first to think "oh I could just hop state lines after a robbery". LOTS of criminals do it. It's not "invalid" because you left the state. It's just more time consuming and difficult for the cops, so for smaller crimes, they tend to get ignored.
Now amp that up to 11 when it comes to hopping countries.
There's a REASON why Edward Snowden and the WikiLeaks guy haven't been arrested and brought back to the US. It's because nations do NOT have police authority in other countries. You can't just send a US cop to go arrest someone on UK soil, for example. It's a violation of that nation's sovereign rights and will REALLY piss them off (it used to be considered an act of war, even). Some countries have extradition treaties to make the process easier (it becomes similar to just hopping state lines in that case. They get the information on the suspect and then arrest him and send him back), but in a lot of cases if you go to a new country it becomes impossible to prosecute you for crimes done in another country and massively inconvenient to arrest you and send you BACK to that country for prosecution. I doubt japan is going to raise enough fuss about this guy sexually assaulting some women that the US or UK will get off their asses and arrest him and send him back. Too much paperwork and effort for them to arrest the guy, considering he didn't commit murder or grand robbery or anything "huge". He "just" sexually assaulted a bunch of women. Hardly something most nations will think is worth the time to chase someone in another country for.
Now, if king moron DOES go back to Japan, he's liable to be arrested for his crimes. But as long as he doesn't go back (or waits until the statue of limitations on the crime expires), it becomes unlikely he'll ever be prosecuted for what he did.
Oh, and before you think "perfect bank heist plan away!", consider that banks have a lot of money and pride and will be able to leverage for your arrest and extradition muuuuuuuch easier than if you had done a crime against someone with much less power and pressure.
(BTW, I'm not a lawyer either.)
