State of 18 U.S. Code § 2257 Record keeping requirements?
 

There have been many changes to 2257 record keeping norms over the past decades, and I'm wondering...

Have ANY Canadian, or any other NON-US, Primary or Secondary Producers EVER had US DOJ contact or visit their place of business, as specified in their "Custodian of Records" statement?

Thanks,
