Could someone please explain Taki to me? Nothing about this guy makes a whole lot of sense!

First of all, did the American FBI even have operational jurisdiction in early '70s Japan? Were there actually multiple branches scattered around in different countries? Does Japan have its own version of an "FBI"? Wouldn't it have made more sense to have him be Interpol?

Second, nothing he actually does aligns with a guy who has authorized police powers! Anytime he goes to investigate Shocker's plans, he goes against any kind of procedure and usually without backup.

Lastly, would any police-like organization have let him work with a Rider? The Rider was originally going to be brainwashed, but got away in time and is using the powers Shocker gave him to fight them! Surely the International Community would rather arrest and possibly experiment on the Rider(s) than let any of them run off on their own, much less with an actual cop/agent!
