How do you introduce evidence
?? Theory ??
I just thought of the "How do you introduce evidence" Q post. What if that is not related to introducing it to courts but to the American people. I can't remember what law it is, but something about some stuff having to stay secret for 72 years to ensure living people aren't harmed by it. Think of this in regards to McAfee.
Not sure what other things are impacted by this 'law' that you're referring to but I do know as a genealogist that US Census records can't be released until 72 years after the census is taken. (I'm anxiously awaiting the 1950 records dump next April.) And yes, it has something to do with minimizing the impact to people who are still living.
99 years in Canada for Census info. Just a FYI.
