Amazon execs destroyed years of evidence before FTC action, agency says

The article doesn't spell it out but it sounds like they got rid of documents THEN the FTC requested them when they started to investigate. If so, unless getting rid of the documents broke some other law then I'm not sure what there is to enforce. If there is no law, there should be. Might be unreasonable to keep things forever but 5-10 years shouldn't be too hard for any company.
