I kind of _hope_ any statutes of limitations would have expired 35 years ago for events then 45 years ago. There's not much point in retaining liability for events that long ago; it's not like you'll ever catch the "crooks", nor likely have the ability to really judge events reasonably anymore by that time.

'course, with the general urge to be "tough on crime" and the inevitable occasional horror-story of truly heinous behavior discovered many decades later there probably isn't a lot of political will to support reasonable statutes of limitations, so I wouldn't be surprised if some of this stuff never expires.
